Review & acceptance
Review time and acceptance
Review time from article dates manuscript dates registered with PubMed · to
Too few articlesOnly 2 articles from the last 24 months carry both submission and acceptance dates, too few for a median
Only articles that were accepted and published are counted, not the time spent on rejected manuscripts, so this usually runs longer than a publisher's "time to first decision".
