  • *Miscellaneous pathology includes angiodysplasia, mucosal prolapse and those who had two or more non-neoplastic outcomes occurring synchronously.

  • †One participant with no pathology detected did not have a definitive f-Hb result and was therefore excluded from analysis from this point onwards.

  • f-Hb, faecal haemoglobin concentration.
