Objectives: To systematically review the comparative statistical performance (discrimination and /or calibration) of prognostic clinical prediction models (CPMs) and clinician judgment (CJ).
Study Design And Setting: We conducted a systematic review of observational studies in PubMed, Medline, Embase, and CINAHL. Eligible studies reported direct statistical comparison between prognostic CPMs and CJ.
Background And Aim: Tamoxifen has been used in the management of breast cancer. The available evidence on the effect of tamoxifen on lipoprotein(a) and apolipoproteins is controversial. Hence, this meta-analysis of randomized controlled trials (RCTs) was conducted to increase the quality of evidence on the effect of tamoxifen on lipoprotein(a) and apolipoproteins.
View Article and Find Full Text PDFBackground And Aim: Conflicting results on the effect of magnesium supplementation on blood pressure have been published in previous meta-analyses; hence, we conducted this umbrella meta-analysis of RCTs to provide a more robust conclusion on its effects.
Methods: Four databases including PubMed, Scopus, EMBASE, and Web of Science were searched to find pertinent papers published on international scientific from inception up to July 15, 2024. We utilized STATA version 17.
Background And Aim: Although various randomized controlled trials (RCTs) have evaluated the effect of raloxifene on apolipoproteins and lipoprotein(a) concentrations in postmenopausal women, the results have been inconsistent and inconclusive. Therefore, we conducted this meta-analysis of RCTs to investigate the effect of raloxifene administration on apolipoproteins and lipoprotein(a) [Lp(a)] concentrations in postmenopausal women.
Methods: Two independent researchers systematically searched the scientific literature (including PubMed/Medline, Scopus, Web of Science, and EMBASE) for English-language randomized controlled trials (RCTs) published up to June 2024.
Background And Aim: Even though the role of D2 (ergocalciferol) on cardiovascular disease risk components has been studied, conflicting results have been reported. Moreover, no single study has studied all these parameters and the role of vitamin D2 individually has not been assessed; hence, this systematic review and meta-analysis of randomized controlled trials was conducted to assess the effect of vitamin D2 supplementation on lipid profile, anthropometric indices, blood pressure, and inflammatory and glycemic biomarkers in humans.
Methods: Web of Science, Scopus, PubMed/Medline, and Embase were searched from database inception to July 2024, and the random effects model, according to the DerSimonian and Laird method, was used to generate combined estimates of the intervention's effect on the outcomes.
Background: Menopause is associated with elevated cardiovascular risk due to the loss of the cardioprotective effect of oestrogens. Postmenopausal women are often prescribed hormone replacement therapy (HRT) in order to control menopause symptoms and correct hormone imbalances; however, HRT can impact serum lipids' concentrations. At present, data on the effect of the administration of medroxyprogesterone acetate plus conjugated equine oestrogens (MPACEE) on the lipid profile in females are uncertain, as the investigations conducted so far have produced conflicting results.
View Article and Find Full Text PDFBackground And Aim: The effects of tamoxifen on the serum levels of hormones and acute phase reactants have been studied previously, but study results have been inconsistent, especially in women with breast cancer. Hence, we conducted this meta-analysis of randomized controlled trials (RCTs) to try to clarify the effects of tamoxifen on estradiol, insulin-like growth factor 1 (IGF-1), sex hormone binding globulin (SHBG), and C-reactive protein (CRP) serum levels in women with breast cancer or at risk of developing breast cancer.
Methods: Databases were systematically searched up to December 2023.
Background: The impacts of subcutaneous Lixisenatide on body weight in patients with type 2 DM, remain inadequately understood; consequently, this systematic review and meta-regression analysis of randomized controlled trials (RCTs) was conducted to evaluate the influence of subcutaneous Lixisenatide administration on BW and BMI values in individuals with Type 2 diabetes.
Methods: A comprehensive literature search was conducted across four databases, spanning from their inception to February 2023. We computed effect sizes employing the random-effects model and reported results in terms of weighted mean differences (WMD) along with their corresponding 95% confidence intervals (CI).
Background: Inconsistencies exist regarding the influence of vitamin D2 (ergocalciferol) supplementation on serum vitamin D levels. These inconsistencies could be attributed to numerous factors, such as dosage, baseline vitamin D levels, and duration of intervention. Hence, this dose-response meta-analysis of randomized controlled trials was conducted to assess the efficacy of vitamin D2 supplementation on vitamin D levels.

Based on the clinical experiences, the treatment of retentive FI in patients with comorbid psychiatric disorders was accelerated when Risperidone was used as treatment for their psychiatric comorbidities; therefore, this study was conducted to evaluate the effect of risperidone in the treatment of retentive FI in children and adolescents.
Methods: In this double-blind, randomized, placebo-controlled trial, 140 patients aged 4-16 years eligible for the study were randomized into two groups, receiving either 0.
Background: The effect of MPA on the lipid profile and CVD risk is still controversial; hence, this comprehensive dose-response meta-analysis of randomized controlled trials was conducted to assess the effect of MPA on lipid profiles in women.
Methods: A comprehensive search was conducted in the following databases: Web of Science, Scopus, PubMed/Medline, and Embase, up to October 20, 2023. A random-effects meta-analysis approach based on the DerSimonian and Laird method was used to compute the combined estimates of the intervention's impact on the lipid profile.
Background: Dulaglutide, a subcutaneously administered glucagon-like peptide 1 receptor agonist, has been hypothesized to lead to weight loss in patients with Type 2 diabetes mellitus (T2DM). However, the consequences of its prescription on body weight (BW) and other anthropometric indices, for example, body mass index (BMI) or waist circumference (WC), have not been completely clarified. Therefore, we aimed to assess the effects of subcutaneous dulaglutide administration on BW, BMI and WC values in T2DM subjects by means of a systematic review and meta-analysis of RCTs.

- The study investigates the impact of phytosterol supplementation on lipid levels, as previous research has shown mixed results in managing dyslipidemia, leading to ongoing debate!* -
- An umbrella meta-analysis was conducted using data from 17 meta-analyses of various studies, finding that phytosterol supplementation significantly lowers levels of LDL cholesterol, total cholesterol, and triglycerides, especially with dosages of 2g/day or more over 8 weeks!* -
- While phytosterols notably decreased harmful cholesterol levels, they did not significantly affect HDL cholesterol levels, indicating potential for use as a complementary therapy for reducing cardiovascular risk, but further research is necessary on its effects in specific populations and any potential side effects.*
Purpose: To date, no study has demonstrated the role of transdermal 17β-estradiol + norethisterone acetate on all of the risk factors for cardiovascular disease in postmenopausal women. To overcome this knowledge gap, a systematic review and meta-analysis were conducted to determine the effects of this combination treatment on BMI, body weight, waist/hip ratio, fibrinogen, factor VII, lipoprotein(a), fasting blood sugar, insulin, HbA, TG, LDL-C, HDL-C, and TC in postmenopausal women.
Methods: PubMed/Medline, SCOPUS, Web of Science, Embase, and Google Scholar were searched for relevant articles published between the inception of each database and April 6, 2023.
Objective: Little evidence exists on the effect of 17beta-estradiol plus norethisterone acetate on all the anthropometric indices. Hence, this systematic review and meta-analysis of Randomized Controlled Trials was conducted to give an evidence-based report on the effect of 17beta-estradiol plus norethisterone acetate on anthropometric indices.
Methods: The literature search was executed in databases including PubMed/Medline, Web of Science, Scopus, Embase, and Google Scholar to recognize clinical trials that examined the influence of 17beta-estradiol plus norethisterone acetate on obesity indices from database inception to Jan 2023.
