Hello, everyone. Please, I need your help. This site is good for getting the CI for NNT, NNH, and Sensitivity and Specificity: http://araw.mede.uic.edu/~alansz/tools.html This site is good for getting the CI for NNT and calculating the CI for a proportion, which you might do for a prognosis study: http://www.graphpad.com/quickcalcs/index.cfm This site is good for calculating OR and its CI: http://www.hutchon.net/ConfidOR.htm But I can't find an online calculator for RR *and* its CI. If anyone knows of one that's easy to use, please let me know.
CI- Confidence Interval; NNT- Number Needed to Treat; NNH- Number Needed to Harm; OR- Odds Ratio; RR- Relative Risk
