  1. Percentages are shown in parentheses; values greater than 100 indicate that more articles were selected for screening than in the original meta-analysis. “Frequently co-cited” refers to citations above a threshold in the ranked list that was chosen such that 100–150 articles needed to be screened (See Methods; Additional file 1: Figure S2)
