Objective

Two randomized controlled trials (RCTs) conducted at journal level have shown that reminding peer reviewers about the 10 most important and underreported reporting items did not improve the reporting quality in published articles.1 With this pooled in-depth analysis of peer reviewer reports, we aimed to assess at what stage the intervention failed.

Design

A subsample of peer reviewer reports from the control group (receiving no reminder) and the intervention group (receiving a reminder of the 10 most important reporting items) were analyzed. In brief, 2 blinded authors independently extracted from peer reviewer reports how many of the 10 key reporting items were flagged by peer reviewers for clarification. The main outcome of this analysis was the mean proportion of the 10 selected reporting items for which at least 1 peer reviewer requested clarification, assessed at the manuscript level. Furthermore, we assessed how many requested changes were later adequately reported in published articles.

Results

Across the RCTs, we had access to peer reviewer reports for 533 manuscripts (265 in the intervention group, assessing comments from 740 peer reviewers; and 268 in the control group, assessing comments from 719 peer reviewers). Our results indicate that reviewers in the intervention group requested clarification on more reporting items than those in the control group. Overall, reviewers in the intervention group flagged 21.1% of the 10 reporting items for clarification compared with 13.1% in the control group (mean difference, 8.0 percentage points (pp); 95% CI, 4.9-11.1 pp). However, the overall mean difference between groups was diluted from 8.0 to 4.2 pp when only assessing accepted and published articles and decreased even further to 2.6 pp when only considering changes that were then implemented by authors of manuscripts (Table 25-0956). Approximately 55% of reporting items that were criticized by peer reviewers were later adequately reported in the published article (intervention group, 173 of 308 [56.2%]; control group, 105 of 197 [53.3%]).

Conclusions

Reminding peer reviewers to check reporting items increased their focus on reporting guidelines, leading to more reporting-related requests in their review reports. However, the effect was diluted during the peer review process (particularly due to rejected articles and requests not being implemented by authors). Journals should therefore make sure that requested clarifications are adequately addressed in revised manuscripts.
