Supplementary Materials for A standardized checklist for reporting meta-analysis in open science era

In the open science era, meta-analysis becomes an important way for integrating open data from different sources. Meanwhile, because of researchers’ high degree of freedom introduced by multiple-steps and multiple-choices in each step of meta-analysis, openness and transparency are crucial for reproducing the results of meta-analysis.

To reflect the transparency and openness of meta-analysis reports published in Chinese journals and improve the transparency and openness of future meta-analysis by Chinese researchers, we developed a Chinese version of a checklist for meta-analysis (Preferred Reporting Items for Open and Reproducible Meta-analysis, PRIOR-MA), which was based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) and the principle of openness and transparency.
