N_AID, N_SID and N_CID are the number of PubChem assays, substances and compounds extracted from scientific articles, respectively; and N_AID-PMID, N_SID-PMID and N_CID-PMID are the number of cross-references from PubChem assays, substances, and compounds to PubMed articles, respectively. N_PMID is the number of unique PubMed articles from which the assay data are extracted
