Receiver operating characteristic curves for advanced neoplasia with a 1-sample FIT, comparing different subgroups; demonstrates no difference in test performance of the 1-sample FIT by age group or gender, or by prior FIT completion. The figure shows ROC curves for a range of hemoglobin concentration cutoffs, from 50 ng/ml (10 μg/g) to 150 ng/ml (30 μg/g). a Comparing adults ages 50-64 to those ages 65-75. b Comparing men and women. c Comparing those who have completed a FIT to those who have not previously completed a FIT. FIT = Fecal immunochemical test; AUC = area under the curve
