Matthew Page and co-authors describe PRISMA 2020, an updated reporting guideline for systematic reviews and meta-analyses.
COVID-19 has disproportionately placed women in academic science on the frontlines of domestic and clinical care compared to men. As a result, women in science are publishing less and potentially acquiring less funding during COVID-19 than compared to before. This widens the pre-existing gap between men and women in prevailing, publication-based me...

This is a protocol for a co‐registered Cochrane and Campbell Review (Methodology). The objectives are as follows: To identify, describe and assess methods for: when to replicate a systematic review; how to replicate a systematic review.
Background:
When a journal receives a duplicate publication, the ability to identify the submitted work as previously published, and reject it, is an assay to publication ethics best practices. The aim of this study was to evaluate how three different types of journals, namely open access (OA) journals, subscription-based journals, and presumed pr...
Purpose
Trustworthy reporting of quadrivalent human papillomavirus (HPV) vaccine trials is the foundation for assessing the vaccine’s risks and benefits. However, several pivotal trial publications incompletely reported important methodological details and inaccurately described the formulation that the control arms received. Under the Restoring In...
Randomised clinical trials are the preferred method for establishing average intervention effects for groups. Using key methodological elements of these trials, n-of-1 trials provide rigorous evidence of intervention effects for individuals.

Objectives:
To generate a comprehensive bank of systematic review (SR) reporting items to inform an update of the PRISMA 2009 statement.
Methods:
We searched the EQUATOR Network library in May 2019 to identify all reporting guidelines for SRs that were published after 2009, regardless of the scope of the guideline. We also conducted a selective...
There is substantial evidence that research studies reported in the scientific literature do not provide adequate information so that readers know exactly what was done and what was found. This problem has been addressed by the development of reporting guidelines which tell authors what should be reported and how it should be described. Many report...
We developed a reporting guideline to provide authors with guidance about what should be reported when writing a paper for publication in a scientific journal using a particular type of research design: the single-case experimental design.

Background
The International Prospective Register of Systematic Reviews (PROSPERO) was launched in February 2011 to increase transparency of systematic reviews (SRs). There have been few investigations of the content and use of the database. We aimed to investigate the number of PROSPERO registrations from inception to 2017, and website usage in th...
Complete and transparent reporting is imperative when assessing the validity of reported treatment effects and other findings of health research. A study’s methods should be described in enough detail so that they can be replicated, the analyses should follow the protocol, and the results should be provided in sufficient detail to be incorporated i...

Background: Scientific editors (i.e., those who make decisions on the content and policies of a journal) have a central role in the editorial process at biomedical journals. However, very little is known about the training needs of these editors or what competencies are required to perform effectively in this role.
Methods: We conducted a survey of...
The dataset lists all of the training needs named by participants (regrouped into categories of similar items) in their respective lists of top 10 training needs from the survey of editors.
The dataset is a summary of the data collected over the three rounds of the Delphi process. We considered items with 80% consensus of 4 or higher (out of 5) as "Included". and items with 90% consensus of 4.5 or higher as "Highly Ranked".
Background
The scholarly publication landscape is changing rapidly. We investigated whether the introduction of an institutional publications officer might help facilitate better knowledge of publication topics and related resources, and effectively support researchers to publish.

Background
Biomedical journals are the main route for disseminating the results of health-related research. Despite this, their editors operate largely without formal training or certification. To our knowledge, no body of literature systematically identifying core competencies for scientific editors of biomedical journals exists. Therefore, we aim...
N-of-1 trials provide a mechanism for making evidence-based treatment decisions for an individual patient. They use key methodological elements of group clinical trials to evaluate treatment effectiveness in a single patient, for situations that cannot always accommodate large-scale trials: rare diseases, comorbid conditions, or in patients using c...
N-of-1 trials are a useful tool for clinicians who want to determine the effectiveness of a treatment in a particular individual. The reporting of N-of-1 trials has been variable and incomplete, hindering their usefulness in clinical decision making and by future researchers. This document presents the CONSORT (Consolidated Standards of Reporting T...
Transparent reporting of all research is essential for assessing the validity of any study. Reporting guidelines are available and endorsed for many types of research but are lacking for clinical pharmacokinetic studies. Such tools promote the consistent reporting of a minimal set of information for end users, and facilitate knowledge translation o...

Background
The Consolidated Standards of Reporting Trials (CONSORT) Statement is intended to facilitate better reporting of randomised clinical trials (RCTs). A systematic review recently published in the Cochrane Library assesses whether journal endorsement of CONSORT impacts the completeness of reporting of RCTs; those findings are summarised her...
Background:
An overwhelming body of evidence stating that the completeness of reporting of randomised controlled trials (RCTs) is not optimal has accrued over time. In the mid-1990s, in response to these concerns, an international group of clinical trialists, statisticians, epidemiologists, and biomedical journal editors developed the CONsolidated...

... The mean overall CONSORT and NPT scores (e.g., the full score is 52), and massage-specific scores (e.g., the full score is 16) were calculated by subgroups and recorded as mean and standard deviations (SD). As indicated in the previous studies, the development of reporting guideline is closely related to the reporting quality of clinical trials [17]. Some scholars have identified that the publish year of guideline and types of journals (e.g., various in the reporting requirements and endorsement degree of the guideline) are the most essential and direct factors related to reporting quality [18,19]. ...
... Despite this, the REFLECT statement has not been adopted to anywhere near the same extent in agriculture as its parent approach (CONSORT) has in health and medicine. Indeed, the CONSORT statement has been cited more than 8000 times (Eldridge et al., 2016), and its use is associated with an improvement in the quality of reporting of RCTs in these fields (Turner et al., 2011). In medicine, poorly designed and/or reported RCTs can lead to overestimation of the treatment effect, diminished quality of pooled analyses (e.g., meta-analyses), and impaired clinical practice decisions (cf. ...

Published systematic reviews [12,13] and pairwise meta-analyses [14][15][16][17] on previous RCTs [18][19][20][21][22][23][24][25] claimed that triple therapy in FDCs, e.g., BDP/FF/G, FF/UMEC/VI and Even if there were no uncovered large-scale RCTs, the past systematic reviews and metaanalyses should be revisited as they were not fully (albeit claimed to be) compliant with the PRISMA 2009 statement [28], let alone PRISMA-NMA statement [29] and PRISMA 2020 statement [30]. They did not meet essential requirements for meta-analysis, e.g., protocol registration [13,16,17], assessment of the study quality by Cochrane risk of bias tool version 2 (RoB 2) [13,31], evidence strength evaluation by the Grades of Recommendations, Assessment, Development and Evaluation (GRADE) [12,13,16,17,32], and statistical analyses such as subgroup analysis and publication bias [12-14, 16, 17]. ...
