If you co-first author a paper, but the journal lists your name second on the official publication despite indicating co-author status, is it ethical to switch the order of their listing to put your name first on your CV or ERAS application? Of course, I would still indicate co-first author status, but just list my name first. Technically we are both first authors, I just wouldn't want this to be seen as deceitful. Also wouldn't want a co-first author paper to be mistakenly viewed as second author though...
