Peptide research statistics and trends

Original statistics on the published science behind the peptides in the Peptide Library: PubMed publications and ClinicalTrials.gov registrations, classified by study type and evidence, counted the same way every time. Every number names the dataset version it comes from, and the methodology shows how to reproduce it.
