I tend to lie more on the end of the spectrum with
@AlbinoHawk DO , writing reviews as a student often takes way more time than it’s worth. original research, even a small case series with a few novel insights, add more to the field than a nonsystematic review. Even for fellows I tend to recommend against spending time writing reviews and prioritizing original research, leaving reviews for later in your career (if you stay in academia).
Furthermore, this “opportunity” feels a little sketchy. What is meant by “may potentially lead to publication?” Unless a review is invited by the journal (usually sent to the senior author who is prominent in the field), then cold-writing a review is often difficult to get published in good journals. And what kind of work are they hoping you can put in yet not even qualify for 1-3 on author list? How many authors is this review going to include?
Bottom line, I would prioritize original research articles over this. If this is your only option for publication, then I’d try to clarify a little bit exactly how much effort this would entail. If its not a ton of effort (as I would hope this wouldn’t be given the low place you would have on the author list) then it may be worth pursuing. This would be more useful than volunteering though, which really should only be done if it makes you happy as it will not move the needle when it comes to applying to residency.
