In 2014, Sightsavers developed the first evidence gap map (EGM) to assess the extent and quality of review-level evidence on cataract relevant to low-and middle-income countries. The EGM identified 52 studies across five broad themes. This paper reports the update of the EGM conducted in 2021 and changes to the extent…

BACKGROUND: The assessment of usability is a complex process that involves several steps and procedures. It is important to standardize the evaluation and reporting of usability procedures across studies to guide researchers, facilitate comparisons across studies, and promote high-quality usability studies. The first s…

BACKGROUND: The knowledge of reporting compliance of systematic reviews with PRISMA guidelines may assist in improving the quality of secondary research in brain AVM management and subsequently application to patient population and clinical practice. This may allow researchers and clinicians to be equipped to appraise…

OBJECTIVE: The current systematic review summarizes reviews on effects of formalized peer support work in clinical psychiatric settings in order to obtain an up-to-date picture of the current state of evidence. METHODS: Search in five electronic databases for relevant literature reviews regarding effects of peer suppo…

A single study rarely suffices to underpin treatment or policy decisions. This creates a strong imperative for systematic reviews. Authors of reviews need a method to synthesize the results of several studies, regardless of whether or which statistical method is used. In this article, we provide arguments for combining…

We set out to determine the quality of existing systematic reviews on multiple pregnancies. We conducted an electronic search in MEDLINE (1951 - 2005), EMBASE (1974 - 2005) and the Cochrane Database for Systematic reviews (2005:2) and a hand-search of reference lists without any language restrictions to identify releva…

OBJECTIVES: The English language is generally perceived to be the universal language of science. However, the exclusive reliance on English-language studies may not represent all of the evidence. Excluding languages other than English (LOE) may introduce a language bias and lead to erroneous conclusions. STUDY DESIGN…

To investigate the feasibility of applying the evidence-based rapid review in studying the nephrotoxicity of Tripterygium wilfordii preparation. We used four methods in relevant studies on the nephrotoxicity of T. wilfordii preparation. The first method had no limitation on any search terms， which was a traditio…

PURPOSE: The aim of this review is to provide an overview of knowledge and knowledge gaps in the field of computer-based alcohol interventions by (1) collating evidence on the effectiveness of computer-based alcohol interventions in different populations and (2) exploring the impact of four specified moderators of effe…

BACKGROUND: Behavioural science can play a critical role in combatting the effects of an infectious disease outbreak or public health emergency, such as the COVID-19 pandemic.

BACKGROUND: Systematic review guidance recommends the use of programme theory to inform considerations of if and how healthcare interventions may work differently across socio-economic status (SES) groups. This study aimed to address the lack of detail on how reviewers operationalise this in practice. METHODS: A metho…

INTRODUCTION: Using data in research often requires that the data first be de-identified, particularly in the case of health data, which often include Personal Identifiable Information (PII) and/or Personal Health Identifying Information (PHII). There are established procedures for de-identifying structured data, but d…

BACKGROUND: Rapid reviews have the potential to overcome a key barrier to the use of research evidence in decision making, namely that of the lack of timely and relevant research. This rapid review of systematic reviews and primary studies sought to answer the question: What are the best methodologies to enable a rapid…
