After many false starts, are these the correct instructions? I had a devil of a time finding them. But it says to follow Vancouver style – – So perhaps you can follow vancouver style, but it doesn’t say to italicized the journal then, I don’t believe? – And here it says if more than 6 list first 3, not if more than 3 list 3? I attach a version of BMJ Case studies where I unbolded the Vol number and italicized the journal, and did change to 4 or more list the first 3 – but to be sure it is correct for all ref types, I would need the original link to the instructions you are trying to follow.
