Range of values in which examiner can be confident that study result consistent w/ reality; Mean + z*standard error of mean; 90%, z = 1.645; 95%, z = 1.96; 99%, z = 2.57; As percent confidence interval increases, range widens; If CI crosses 1, may be no association between risk and disease; If CI crosses 0, may be no difference between two treatments
