Confidence intervals of the relative risk and odds ratio can predict when the optimal information size in a meta-analysis is not met.

Objectives: We sought to empirically evaluate whether the width of confidence interval (CI) of the relative risk (RR) and odds ratio (OR) can obviate the need for calculating the optimal information size (OIS) when making Grading of Recommendations Assessment, Development and Evaluation imprecision judgments.

Study Design And Setting: We analyzed a convenience sample of meta-analyses extracted from the Cochrane Database of Systematic Reviews. From each meta-analysis, we calculated OIS based on relative risk reductions (RRRs) of 15%-50% and evaluated the ratio of upper to lower 95% CI boundaries of RR (RR CI ratio) and OR (OR CI ratio).

Inhaled Reliever Therapies for Asthma: A Systematic Review and Meta-Analysis.

Importance: The optimal inhaled reliever therapy for asthma remains unclear.

Objective: To compare short-acting β agonists (SABA) alone with SABA combined with inhaled corticosteroids (ICS) and with the fast-onset, long-acting β agonist formoterol combined with ICS for asthma.

Data Sources: The MEDLINE, Embase, and CENTRAL databases were searched from January 1, 2020, to September 27, 2024, without language restrictions.

ASH living guidelines on use of anticoagulation for thromboprophylaxis in patients with COVID-19: executive summary.

COVID-19-related critical and acute illness are associated with an increased risk of venous thromboembolism (VTE). These evidence-based recommendations of the American Society of Hematology (ASH) are intended to support patients, clinicians, and other healthcare professionals in decisions about the use of anticoagulation for thromboprophylaxis in patients with COVID-19-related critical illness, acute illness, and those being discharged from the hospital, who do not have suspected or confirmed VTE. ASH formed a multidisciplinary panel, including three patient representatives, and applied a conflicts of interest management policy to minimize potential bias.

Cross-cultural adaptation and validation to Spanish of the PANELVIEW instrument to evaluate the health guidelines development process.

Objectives: The PANELVIEW questionnaire identifies the strengths and weaknesses of the process and methods used for developing health guidelines from the guideline development group's perspective. To expand its use, PANELVIEW ideally should be available in different languages. We aimed to cross-culturally adapt PANELVIEW into Spanish and assess its acceptability, validity, and reliability.

Protocol for a Series of Systematic Reviews and Network Meta-analyses of Randomized Controlled Trials of Medications for Patients with Overactive Bladder Symptoms.

Multiple randomized controlled trials (RCTs) have examined first-line pharmacological agents such as anticholinergics and β3 agonists for the management of overactive bladder symptoms (OAB). Although earlier systematic reviews and (network) meta-analyses aimed to summarize the evidence, a substantial number of trials were not included, so a comprehensive and methodologically rigorous evaluation of the comparative effectiveness of all first-line pharmacological treatments is lacking. We aim to conduct a series of systematic reviews and network meta-analyses (NMAs) for a comprehensive assessment of the effectiveness and safety of first-line pharmacological treatments for OAB.

Pedagogic Strategies and Contents in Medical Writing/Publishing Education: A Comprehensive Systematic Survey.

Workshops or training sessions on medical writing and publishing exist worldwide. We aimed to evaluate published articles about such workshops and examine both the content and teaching strategies employed. We searched ISI Web of Science, Ovid EMBASE, ERIC, Ovid Medline, and the grey literature.

"Mastectomy for individuals with gender dysphoria below 26 years of age: A systematic review and meta-analysis".

Background: Gender dysphoria (GD) refers to psychological distress associated with the incongruence between one's sex and one's gender. In response to GD, birth-registered females may choose to undergo mastectomy. In this systematic review, we summarize and assess the certainty of the evidence on the effects of mastectomy.

Assessing the Certainty of the Evidence in Systematic Reviews: Importance, Process, and Use.

When interpreting results and drawing conclusions, authors of systematic reviews should consider the limitations of the evidence included in their review. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach provides a framework for the explicit consideration of the limitations of the evidence included in a systematic review, and for incorporating this assessment into the conclusions. Assessments of certainty of evidence are a methodological expectation of systematic reviews.

Corticosteroids for the Treatment of Internal Temporomandibular Joint Disorders: A Systematic Review and Network Meta-Analysis.

We evaluated the comparative effectiveness of all intra-articular injection corticosteroids for treating internal temporomandibular joint (TMJ) disorders. : We searched MEDLINE, CENTRAL, EMBASE, SCOPUS, and LILACS through December 2023. We included randomized clinical trials (RCTs) enrolling patients with symptomatic internal disorders of the TMJ comparing any type of intra-articular corticosteroid therapy against another or to another minimally invasive therapy.

GRADE guidance 39: using GRADE-ADOLOPMENT to adopt, adapt or create contextualized recommendations from source guidelines and evidence syntheses.

Background And Objective: The Grading of Recommendations, Assessment, Development and Evaluations (GRADE)-ADOLOPMENT methodology has been widely used to adopt, adapt, or de novo develop recommendations from existing or new guideline and evidence synthesis efforts. The objective of this guidance is to refine the operationalization for applying GRADE-ADOLOPMENT.

Methods: Through iterative discussions, online meetings, and email communications, the GRADE-ADOLOPMENT project group drafted the updated guidance.

Introduction to network meta-analysis: understanding what it is, how it is done, and how it can be used for decision-making.

Network meta-analysis (NMA), a statistical technique that allows systematic reviewers to simultaneously compare more than two alternatives, makes use of indirect evidence from studies comparing interventions of interest to a common comparator. The capacity for multiple simultaneous comparisons makes NMA appealing for evidence-based decision-makers. This article, aimed at users of SRs with NMAs and at those who are considering conducting SRs with NMAs, provides an introductory level overview of this topic.

Systematic reviews of the literature: an introduction to current methods.

Systematic reviews are a type of evidence synthesis in which authors develop explicit eligibility criteria, collect all the available studies that meet these criteria, and summarize results using reproducible methods that minimize biases and errors. Systematic reviews serve different purposes and use a different methodology than other types of evidence synthesis that include narrative reviews, scoping reviews, and overviews of reviews. Systematic reviews can address questions regarding effects of interventions or exposures, diagnostic properties of tests, and prevalence or prognosis of diseases.

Outpatient vs inpatient management of preterm prelabor rupture of membranes: A systematic review and meta-analysis.

Introduction: To compare neonatal, obstetrical, and maternal outcomes associated with outpatient vs inpatient management of pregnancies with preterm prelabor rupture of membranes (PPROM).

Material And Methods: A search of MEDLINE, EMBASE, the Cochrane Database and Central Register from January 1, 1990 to July 31, 2023 identified randomized controlled trials (RCTs) and cohort studies comparing outpatient with inpatient management for pregnant persons diagnosed with PPROM before 37 weeks' gestation. No language restriction was applied.

Efficacy and Safety of Systemic Corticosteroids for Urticaria: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

Background: Short courses of adjunctive systemic corticosteroids are commonly used to treat acute urticaria and chronic urticaria flares (both with and without mast cell-mediated angioedema), but their benefits and harms are unclear.

Objective: To evaluate the efficacy and safety of treating acute urticaria or chronic urticaria flares with versus without systemic corticosteroids.

Methods: We searched the MEDLINE, EMBASE, CENTRAL, CNKI, VIP, Wanfang, and CBM databases from inception to July 8, 2023, for randomized controlled trials of treating urticaria with versus without systemic corticosteroids.

Reporting of health equity considerations in vaccine trials for COVID-19: a methodological review.

Background And Objectives: An emerging body of randomized controlled trials (RCTs) on COVID-19 vaccines has served as the evidence base for public health decision-making. While it is recommended that RCTs report results by health equity stratifiers to reduce bias in health care and gaps in research, it is unknown whether this was done in COVID-19 vaccine trials. To critically examine the use of health equity stratifiers in COVID-19 vaccine trials.

Conduct and reporting of multivariate network meta-analyses: a scoping review.

Objectives: Combining multivariate and network meta-analysis methods simultaneously in a multivariate network meta-analysis (MVNMA) provides the methodological framework to analyze the largest amount of evidence relevant to decision-makers (i.e., from indirect evidence and correlated outcomes).

How do network meta-analyses address intransitivity when assessing certainty of evidence: a systematic survey.

Objectives: To describe how systematic reviews with network meta-analyses (NMAs) that used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) NMA approach addressed intransitivity when assessing certainty of evidence.

Design: Systematic survey.

Data Sources: Medline, Embase and Cochrane Database of Systematic Reviews from September 2014 to October 2022.

Hypophosphatasia diagnosis: current state of the art and proposed diagnostic criteria for children and adults.

Background: This manuscript provides a summary of the current evidence to support the criteria for diagnosing a child or adult with hypophosphatasia (HPP). The diagnosis of HPP is made on the basis of integrating clinical features, laboratory profile, radiographic features of the condition, and DNA analysis identifying the presence of a pathogenic variant of the tissue nonspecific alkaline phosphatase gene (ALPL). Often, the diagnosis of HPP is significantly delayed in both adults and children, and updated diagnostic criteria are required to keep pace with our evolving understanding regarding the relationship between ALPL genotype and associated HPP clinical features.

Proposed diagnostic criteria for the diagnosis of hypophosphatasia in children and adolescents: results from the HPP International Working Group.

Hypophosphatasia (HPP) is a rare inborn error of metabolism that presents variably in both age of onset and severity. HPP is caused by pathogenic variants in the ALPL gene, resulting in low activity of tissue nonspecific alkaline phosphatase (TNSALP). Patients with HPP tend have a similar pattern of elevation of natural substrates that can be used to aid in diagnosis.

Compelling evidence from meta-epidemiological studies demonstrates overestimation of effects in randomized trials that fail to optimize randomization and blind patients and outcome assessors.

Objectives: To investigate the impact of potential risk of bias elements on effect estimates in randomized trials.

Study Design And Setting: We conducted a systematic survey of meta-epidemiological studies examining the influence of potential risk of bias elements on effect estimates in randomized trials. We included only meta-epidemiological studies that either preserved the clustering of trials within meta-analyses (compared effect estimates between trials with and without the potential risk of bias element within each meta-analysis, then combined across meta-analyses; between-trial comparisons), or preserved the clustering of substudies within trials (compared effect estimates between substudies with and without the element, then combined across trials; within-trial comparisons).

How To Read a Network Meta-analysis.

Network meta-analysis (NMA) expands upon traditional meta-analysis by integrating three or more interventions. This allows comparing interventions using evidence from trials that have compared pairs of interventions directly, and indirect evidence through common comparators. We provide an overview of NMA concepts and considerations when interpreting results from a systematic review with a NMA and applying them to clinical practice.
