Degree of Usefulness and Reliability

Although observational studies cannot be used as reliable sources to make statements of fact about the "safety, efficacy, or effectiveness" of a practice, they can still be of use for some other things:

"hey can: 1) provide information on “real world” use and practice; 2) detect signals about the benefits and risks of... use in the general population; 3) help formulate hypotheses to be tested in subsequent experiments; 4) provide part of the community-level data needed to design more informative pragmatic clinical trials; and 5) inform clinical practice."
