Fvasconcellos, I'm not sure about the [] round the PMIDs. Eubulides has also questioned them. I think that the fact that the PMIDs are blue and have a hyperlink symbol is enough of a visual distraction without [] markup, and presumably colour and link symbols aren't governed by the Vancouver style. I see you moved the PMIDs after the DOIs. Don't mind either way on that. I'm not sure what punctuation should surround the DOI and PMID bits. Do you think we need a trailing period after the PMID number? Thoughts? I'm happy to make any changes so I'm not asking you to revert and I'm grateful for your help here (which I asked for!)°
