Iowa SHL feasibility study results. Estimated operating characteristics for optimal algorithms based on data sets in each sex/specimen type stratum. The average (Mean) and standard deviation (SD) of the number of tests are provided. Stratum sample sizes are shown. The estimated efficiency (EFF) is the mean number of tests divided by . Accuracy probabilities (1 = CT; 2 = NG) are estimated by averaging over the 5000 data sets
