Cumulative distribution of scores. For each confidence score cutoff, the number of chemicals (top) and protein–chemical interactions (bottom) that have at least this confidence score in the human protein–chemical network. For example, there are 110 000 chemicals with a high-confidence interaction (score at least 0.7). Note that interactions with confidence scores below 0.15 are not stored in STITCH. Steps in the data correspond to large numbers of compounds that have a maximum score in manually curated databases or the ChEMBL database (with different confidence levels).
