I am proofreading a grant from another researcher. This is going to be submitted to the NIH which follows AMA guidelines. A particular, long report is providing her several of the researcher's citations. I asked for page references to some of her stats since I couldn't read the whole thing, and I needed to verify her correctness in interpreting them. This document is hundreds of pages long and she cites 3 different sections in the article.
1) Is it necessary for her to indicate the actual pages in the citations
2) How to cite the same document at several locations?
