Key figures
Citations are those received so far by the papers published in these years, so the most recent years have had less time to collect them. Two-year mean citedness is OpenAlex's measure of how often recent papers are cited; it is similar in idea to, but not the same as, an impact factor. Citation impact trend compares how often a journal's 2024-25 papers are cited with how often its 2021-22 papers were cited, each measured against all ranked journals' papers of the same years, so newer papers are not at a disadvantage. "Not enough papers" or "Not enough data" means fewer than 50 papers in one of the two-year periods (or fewer than 50 citations to the earlier papers). Values above +300% or below -90% are shown as "+300% or more" or "-90% or less": such extreme values come from very low citation counts for the earlier papers.
