I've always listed poster presentations that were not
presented by me under the "Abstracts" heading of my CV. The only things listed under the heading of "Poster Presentations" are ones I've actually presented myself. It's what was recommended by people in my previous labs. My personal opinion is that listing something as a poster presentation implies that you yourself presented the data at a conference.

Agreed. I don't think it'll matter whether you list it as a poster or as an abstract OP.
