What the numbers say
Recent volumes show fewer papers and weaker citation performance than before.
Both output and citation impact declined. If you prioritise citation visibility, treat submissions with added caution. Smoking Behavior and Cessation rose from 0.0% to 7.0% of what the journal runs. Authors working on smoking cessation may find their topic better represented now. Recent titles increasingly carry megabank · underweight · tohoku · cohort · nationwide. Expect more large cohort and nationwide studies among recent articles. Gold open access accounts for 100.0%. Prepare for your paper to be openly accessible on publication.
