If you are just collecting data and handing it to a coordinating center for analysis, then "yes", it isn't as highly regarded as bench research because it isn't really research, it is more like clinical care except that you are observing subjects, not patients (subjects can be patients but don't confuse clinical research with clinical care).
If you were working with an investigator on retrospective chart review studies or small projects where you come up with the hypothesis, have some input in how the study is designed and conducted, and do some of the analysis yourself (even if it is only descriptive stats) then that sort of clinical research is as good or better than bench reserach. The point is, you should have some participation in the scientific method. Doing data collection on a clinical trial (where the sponsor provides you with eveything) is the clinical equivalent to washing labware.
