Receiver operating characteristic curves for advanced neoplasia, comparing 1-sample FIT and 2-sample FIT; demonstrates that there is no significant difference between ROC curves for 1-FIT and 2-FIT. Each line represents the highest fecal immunochemical hemoglobin measurement from the specified number of fecal samples collected and the corresponding maximum sensitivity and specificity at a given hemoglobin concentration cutoff, from 50 ng/ml (10 μg/g) to 150 ng/ml (30 μg/g). FIT-1 = first fecal immunochemical test sample collected; FIT-2 = both fecal immunochemical test samples collected; AUC = area under the curve
