About these figures

Impact factor is the latest value LetPub lists. CAS zone is the major-category zone of the Chinese Academy of Sciences journal ranking, 2025 upgraded edition by default and switchable to the 2026 Xinrui edition; Top and review-journal flags are kept per edition.
Review time is first the median from submission to acceptance of the journal's own articles from the last 24 months (Crossref / PubMed dates, at least 10 articles), then the publisher's stated submission-to-acceptance, final-decision or post-review decision time, then the community's average report. A publisher's "time to first decision" includes desk rejections and is used only when nothing else exists. Each source is labelled.
APC is taken from DOAJ, OpenAlex, the publisher's website and LetPub, in that order; a hybrid journal's APC applies only to articles published open access.
Articles per year is OpenAlex's count for the last complete year, or LetPub's annual article count when that is missing.
