Reproducibility success rates at the article level for different collapsing criteria.

In this table, N is the number of articles meeting each collapsing criterion, “success rate (%), all” expresses N as a percentage of all 177 meta-analysis articles in the sample, and “success rate (%), subset” expresses N as a percentage of the subset of 26 articles with shared data and code. In the first three columns of this table, the articles with data and code judged irrelevant to the target results were considered failures by default. In the last three columns, reproduction attempts where we wrote new code to reproduce the target results were included in success calculations.
