Core publications, fractional counting, field-normalised citation shares. Brackets show Leiden’s stability interval. Collaboration and open-access shares use full counting and aren’t field-normalised. Retraction counts come from the Retraction Watch database and include publishers’ mass retractions as well as honest-error retractions; a retraction is not by itself evidence of misconduct, and the count is never scored.
