Using qFIT as a test in symptomatic patients defines 2 groups:
qFIT positive, with a risk of CRC of 16%
qFIT negative group (without IDA or a mass), with a risk that is below the asymptomatic population i.e. 1cm, Inflammatory Bowel Disease and Cancer):
qFIT400 - >50% chance of significant pathology

Thanks. This is brilliant.
Does it mean 68 colonoscopy referrals were correct, out of n=2000? In layman's terms, 3.4% correct referral rate?
BMC looks like a useful resource, thanks for bringing it to light.
