A new PeerJ article claims to have looked at the indexing of 481 biomedical open access journals. It’s claimed that 86.7% were found to be listed in the DOAJ, while 36.5% were indexed in PubMed Central. However, given the level of detail in the paper itself, it seems odd to find that there’s no list given of the journal titles and URLs checked. They’re certainly not in the supplemental data file which is very misleadingly titled “All journals listed in the included databases, along with journal data”.
