Table 2.
Reclassification table for individuals with and without AN. FIT cut-off concentration is 20 µg Hb/g faeces. The risk positivity threshold (risk = 0.2524) was selected to generate an identical number of positives compared to FIT at 20 µg Hb/g faeces (58 individuals). Using either FIT or risk would lead to detection of AN in 28 of 58 individuals. Twelve individuals would be reclassified.
