Challenges of identifying unpublished data from clinical trials: Getting the best out of clinical trials registers and other novel sources
Research Synthesis Methods - Tập 9 Số 4 - Trang 561-578 - 2018
Clinical trial data are essential for assessments of the effectiveness of health
care interventions. Information about ongoing or completed, but not yet formally
published, trials has been more difficult to identify until the development of
clinical trials registers and portals. This paper summarises research evidence
on identifying sources of trial data, how and when to search those sources, and
...
Applications of text mining within systematic reviews

Searching for grey literature for systematic reviews: challenges and benefits
Research Synthesis Methods - Tập 5 Số 3 - Trang 221-234 - 2014
There is ongoing interest in including grey literature in systematic reviews.
Including grey literature can broaden the scope to more relevant studies,
thereby providing a more complete view of available evidence. Searching for grey
literature can be challenging despite greater access through the Internet,
search engines and online bibliographic databases. There are a number of
publications that l...
revtools: An R package to support article screening for evidence synthesis
Research Synthesis Methods - Tập 10 Số 4 - Trang 606-614 - 2019
The field of evidence synthesis is growing rapidly, with a corresponding
increase in the number of software tools and workflows to support the
construction of systematic reviews, systematic maps, and meta‐analyses. Despite
much progress, however, a number of problems remain, including slow integration
of new statistical or methodological approaches into user‐friendly software, low
prevalence of op...
A basic introduction to fixed-effect and random-effects models for meta-analysis

A scoping review of scoping reviews: advancing the approach and enhancing the consistency
Research Synthesis Methods - Tập 5 Số 4 - Trang 371-385 - 2014
BackgroundThe scoping review has become an increasingly popular approach for
synthesizing research evidence. It is a relatively new approach for which a
universal study definition or definitive procedure has not been established. The
purpose of this scoping review was to provide an overview of scoping reviews in
the literature.MethodsA scoping review was conducted using the Arksey and
O'Malley fra...
Critical interpretation of Cochran's Q test depends on power and prior assumptions about heterogeneity

Methods for the joint meta‐analysis of multiple tests
Research Synthesis Methods - Tập 5 Số 4 - Trang 294-312 - 2014
Existing methods for meta‐analysis of diagnostic test accuracy focus primarily
on a single index test. We propose models for the joint meta‐analysis of studies
comparing multiple index tests on the same participants in paired designs. These
models respect the grouping of data by studies, account for the within‐study
correlation between the tests' true‐positive rates (TPRs) and between their
false‐...

Introduction, comparison, and validation of Meta‐Essentials : A free and simple tool for meta‐analysis
Research Synthesis Methods - Tập 8 Số 4 - Trang 537-553 - 2017
We present a new tool for meta‐analysis, Meta‐Essentials, which is free of
charge and easy to use. In this paper, we introduce the tool and compare its
features to other tools for meta‐analysis. We also provide detailed information
on the validation of the tool. Although free of charge and simple,
Meta‐Essentials automatically calculates effect sizes from a wide range of
statistics and can be used...
