The standard approach to calculating confidence intervals for odds ratios is to treat them as log-normally distributed. Your data are consistent with this, specifically, In the test group, log parameters μ ^ T = 3.08 and σ ^ T = 1 are consistent with an estimated odds ratio of exp. . ( μ ^ T) ≈ 21.76 and a confidence interval from exp.
