Fig. 3From: Population-based colorectal cancer screening programmes using a faecal immunochemical test: should faecal haemoglobin cut-offs differ by age and sex?Relation between saving colonoscopies (SC) and lesion loss upon increasing the faecal haemoglobin concentration cut-off by sex. Dotted lines represent lesion detection rates (for colorectal cancer (CRC) and advanced adenoma (AA)) and solid lines saved colonoscopies. The left Y axis represents lesion detection rate and the right Y 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 positivity rateBack to article page
