A scoping review of scoping reviews: advancing the approach and enhancing the consistency Tập 5 Số 4 - Trang 371-385 - 2014
Mai Pham, Andrijana Rajić, Judy Greig, Jan M. Sargeant, Andrew Papadopoulos, Scott A. McEwen
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

Robust variance estimation in meta‐regression with dependent effect size estimates Tập 1 Số 1 - Trang 39-65 - 2010
Larry V. Hedges, Elizabeth Tipton, Matthew C. Johnson
AbstractConventional meta‐analytic techniques rely on the assumption that effect
size estimates from different studies are independent and have sampling
distributions with known conditional variances. The independence assumption is
violated when studies produce several estimates based on the same individuals or
there are clusters of studies that are not independent (such as those carried
out by th... hiện toàn bộ
Introduction, comparison, and validation of Meta‐Essentials: A free and simple tool for meta‐analysis Tập 8 Số 4 - Trang 537-553 - 2017
Robert Suurmond, Henk van Rhee, Tony Hak
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... hiện toàn bộ
Searching for grey literature for systematic reviews: challenges and benefits Tập 5 Số 3 - Trang 221-234 - 2014
Quenby Mahood, Dwayne Van Eerd, Emma Irvin
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... hiện toàn bộ
Pooling health‐related quality of life outcomes in meta‐analysis—a tutorial and review of methods for enhancing interpretability Tập 2 Số 3 - Trang 188-203 - 2011
Kristian Thorlund, Stephen D. Walter, Bradley C. Johnston, Toshi A. Furukawa, Gordon Guyatt
Background– Meta‐analyses of health‐related quality of life (HRQL) outcomes
present difficulties in interpretation when studies use different instruments to
measure the same construct. Presentation of results in standard deviation units
(standardized mean difference) is widely used but is limited by vulnerability to
differential variability in populations enrolled and interpretational
challenges.O... hiện toàn bộ
Graphical displays for meta‐analysis: An overview with suggestions for practice Tập 1 Số 1 - Trang 66-80 - 2010
Judith Anzures‐Cabrera, Julian P. T. Higgins
AbstractMeta‐analyses are fundamental tools for collating and synthesizing large
amounts of information, and graphical displays have become the principal tool
for presenting the results of multiple studies of the same research question. We
review standard and proposed graphical displays for presentation of
meta‐analytic data, and offer our recommendations on how they might be presented
to provide ... hiện toàn bộ
revtools: An R package to support article screening for evidence synthesis Tập 10 Số 4 - Trang 606-614 - 2019
Martin J. Westgate
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... hiện toàn bộ
