From: Population-based colorectal cancer screening programmes using a faecal immunochemical test: should faecal haemoglobin cut-offs differ by age and sex?

Fig. 4

Relation between saving colonoscopies (SC) and lesion losses upon increasing the cut-off level of the FIT by sex and age group. Dotted lines express lesion detection rates (colorectal cancer (CRC) and advanced adenoma (AA)) and solid lines saved colonoscopies. The left Y-axis represents lesion detection rate and the right axis the percentage of colonoscopies saved. Saving Colonoscopies: the percentage of colonoscopies that will not be performed in the programme by increasing the f-Hb cut-off, due to the reduction of positive rate
