Wagenaar et al. adjust for outliers by excluding a few estimates, but they fail to address publication bias.
Poor data quality raises doubt on the ability of trial registration to meet the challenge of achieving research transparency, including the ability to adequately address publication bias and selective reporting, and reducing the amount of wasted research [37] [39].
Finally, this analysis addresses publication rates among large registered trials.
To address publication bias, Egger's test and funnel plots will be calculated with the EPIDAT 3.1 software.
Several recent articles addressing publication guidelines for optimized multicolor immunofluorescence panels might aid in raising further awareness [ 32].
In conclusion, addressing publication bias and related small-study effects in NMAs was feasible in this case study.
The authors suggest strategies to address publication bias, such as mandatory publication of study protocols, research results or the reasons why no results were obtained.
To address publication bias, we also sought out and reviewed unpublished and gray literature, particularly local research, from Asia, Central America, and Africa provided by household-energy experts.
Standard approaches for addressing publication bias would have been to contact lead authors and researchers in this field to enquire into such relevant unpublished work.
The most common approaches to address publication bias in a meta-analysis include ignoring the issue and applying methods based on the funnel plot.
