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."

Famous quotes containing the words degree of, degree and/or usefulness:
“In all pointed sentences, some degree of accuracy must be sacrificed to conciseness.”
—Samuel Johnson (1709–1784)
“The world is burdened with young fogies. Old men with ossified minds are easily dealt with. But men who look young, act young and everlastingly harp on the fact that they are young, but who nevertheless think and act with a degree of caution that would be excessive in their grandfathers, are the curse of the world. Their very conservatism is secondhand, and they don’t know what they are conserving.”
—Robertson Davies (b. 1913)
“Human life consists in mutual service. No grief, pain, misfortune, or “broken heart,” is excuse for cutting off one’s life while any power of service remains. But when all usefulness is over, when one is assured of an unavoidable and imminent death, it is the simplest of human rights to choose a quick and easy death in place of a slow and horrible one.”
—Charlotte Perkins Gilman (1860–1935)
