Exploring transparent reporting and data availability in systematic reviews to identify subgroup evidence: imaging for suspected hepatocellular carcinoma in the non-cirrhotic liver.

We aim to illustrate the role of complete and transparent reporting coupled with access to data sourced from published systematic reviews, especially assisting in the identification of evidence for subgroups within the context of a rare disease. To accomplish this principle, we provide a real-world example encountered during the revision of the Dutch clinical practice guideline for hepatocellular carcinoma. Specifically, we retrieved insights from two Cochrane reviews to identify direct evidence concerning the diagnostic test accuracy of computed tomography and magnetic resonance imaging for detecting hepatocellular carcinomas in suspected patients without liver cirrhosis.

Introducing re-weighted range voting in clinical practice guideline prioritization: Development and testing of the re-weighted priority-setting (REPS) tool.

We aimed to develop and test a tool based on the re-weighted range voting mechanism to prioritize items (i.e. key questions) in a priority-setting assessment for clinical practice guidelines.

Designing tailored maintenance strategies for systematic reviews and clinical practice guidelines using the Portfolio Maintenance by Test-Treatment (POMBYTT) framework.

Background: Organizations face diverse contexts and requirements when updating and maintaining their portfolio, or pool, of systematic reviews or clinical practice guidelines they need to manage. We aimed to develop a comprehensive, theoretical framework that might enable the design and tailoring of maintenance strategies for portfolios containing systematic reviews and guidelines.

Methods: We employed a conceptual approach combined with a literature review.

A Delphi consensus checklist helped assess the need to develop rapid guideline recommendations.

Background And Objectives: We aimed to develop a checklist to aid guideline developers in determining which scientific or societal cause ("triggers") are relevant when considering to initiate a rapid recommendation procedure.

Methods: We conducted a two-round modified Delphi procedure with a panel of Dutch guideline experts, clinicians, and patient representatives. A previously conducted systematic literature review and semistructured interviews with four science journalists were used to generate a list of potential items.

Effectiveness of contact tracing apps for SARS-CoV-2: a rapid systematic review.

Objective: To systematically review evidence on effectiveness of contact tracing apps (CTAs) for SARS-CoV-2 on epidemiological and clinical outcomes.

Design: Rapid systematic review.

Data Sources: EMBASE (OVID), MEDLINE (PubMed), BioRxiv and MedRxiv were searched up to 28 October 2020.

Data sources and methods used to determine pretest probabilities in a cohort of Cochrane diagnostic test accuracy reviews.

Background: A pretest probability must be selected to calculate data to help clinicians, guideline boards and policy makers interpret diagnostic accuracy parameters. When multiple analyses for the same target condition are compared, identical pretest probabilities might be selected to facilitate the comparison. Some pretest probabilities may lead to exaggerations of the patient harms or benefits, and guidance on how and why to select a specific pretest probability is minimally described.

Instruments Measuring Physical Activity in Individuals Who Use a Wheelchair: A Systematic Review of Measurement Properties.

Objective: To systematically review the evidence evaluating validity or reliability of self-reported and device-based instruments, to measure physical activity (PA) in individuals who use a wheelchair, and to make recommendations for the selection of PA outcomes tools.

Data Sources: PubMed, Embase, and CINAHL were systematically searched.

Study Selection: Studies reporting measurement properties of instruments to assess PA in individuals who use a wheelchair.

Concurrent validity and reliability of wireless instrumented insoles measuring postural balance and temporal gait parameters.

Background: The OpenGo seems promising to take gait analysis out of laboratory settings due to its capability of long-term measurements and mobility. However, the OpenGo's concurrent validity and reliability need to be assessed to determine if the instrument is suitable for validation in patient samples.

Methods: Twenty healthy volunteers participated.
