Peptide Sentinel

Data-led reporting on the peptide research record

Four investigations into the peptide research record

Measurable facts about the peptide research literature and the public record around it, with the dataset behind every figure.

Three of the four pieces below examine this portfolio's own corpus, which is stated on every page rather than left for a reader to notice. A publication that measures other people's work and not its own is doing rhetoric, not measurement.

    12 rows out of 188,556

How this publication counts

Every figure on this site is generated by a script in the open, from files a reader can download. Every piece states what was counted, from which files, on what date and with what query, and every piece states what the analysis cannot show. No full texts were read, so nothing here is a claim about what any study concluded.

The rules are written down once on the methods page, and the 77 compounds behind three of the four pieces are the corpus this portfolio publishes from.
