Read these numbers carefully
- These times describe articles the journal accepted. Rejected manuscripts never appear in public data, so they cannot tell you how long a rejection takes.
- Dates are the ones the publisher deposited with PubMed. Some publishers record the date a revised manuscript arrived as the submission date, which makes review look faster.
- Invited articles and special issues can move faster than regular submissions.
