n=488 assays		Predicted (this work)
Positive	Negative
There are 488 identical in vivo assays with phrases that were manually assigned by database curators12 (‘actual’) in comparison to the disease/phenotype or reference animal model annotation performed in this work (‘predicted’). The remaining 12 assays (out of 500) had been classified as in vivo by Zwierzyna & Overington12 but are in fact considered to be in vitro or ex vivo assays.
