Fit false positive rate
WebBackground: Colorectal cancer screening by fecal immunochemical tests (FITs) is hampered by frequent false-positive (FP) results and thereby the risk of complications and strain on colonoscopy capacity. Hemorrhoids might be a plausible cause of FP results. Objective: To determine the contribution of hemorrhoids to the frequency of FP FIT results. WebThe true positive rate, also known as sensitivity or recall in machine learning, is a metric that measures the percentage of actual positives that are accurately identified. More advanced techniques, on the other hand, are feasible. If all low confidence predictions are going to be manually checked, allocating a manual labor cost to them and ...
