It's a so-called meta-analysis, looking at a bunch of other studies and trying to create a baseline of known knowledge which will inform future individual focused studies.

Having this kind of body of curated knowledge means, for example, that a funding agency might be more willing to sponsor further specific research, i.e. you could say 'here's our plan for giving subjects doses of x amounts to study the threshold where visual perception becomes strongly altered, based on this prior work' and so on.
