Evidence sources: SCImago. SCImago's count is a source-reported aggregate figure; Crossref/OpenAlex/PubMed counts are distinct article records JCF Labs observed via each provider's own free API — none is guaranteed to be that journal's complete output for the year, and providers may disagree (this is expected, not an error). See this journal's own source evidence above for full context.
