Cautionary Advisory: Detecting Predatory Journals

Commercial entities occasionally publish in pay-to-play "predatory journals" without legitimate peer review, later marketing expensive unproven treatments as "proven by international science." Key test: verify indexing in PubMed/MEDLINE, inspect editorial board credentials, and beware of journals offering guaranteed rapid publication for a fee.
