hi...
quoting
"EBM recognizes that observational studies may provide high-quality
evidence if treatment effects are sufficiently large, consistent and
rapid."
from Karanicolas PJ, Kunz R, Guyatt GH. Point: evidence-based
medicine has a sound scientific base. Chest. 2008 May;133(5):1067-71.
i want to know more about the precise definition of "treatment effects
are sufficiently large, consistent and rapid."? it sounds so fuzzy..
best regards.
