aAll times and rates were recorded or calculated in minutes

bCuration rate = Time spent per curated article. SD = standard deviation.

cRejection rate = Time spent per rejected article.

Total data extracted = total number of chemical-gene, chemical-disease, and gene-disease interactions.

dData extraction rate = macro-average of individual rates of the number of interactions for each curatable article.
