Table 1. Disease prediction for the prospective validation cohort from secondary care USC referral patients. Test sensitivity and specificity (95% confidence intervals according to initial diagnostic test)

	n, total	Sensitivity	Specificity
Colonoscopy	248	95.7 (78.1% to 99.9%)	69.3 (63.8% to 76.1%)
Colonoscopy and CTC	405	89.7 (72.7% to 97.8%)	65.7 (60.7% to 70.5%)

CTC = computed tomography colonoscopy. USC = urgent suspected cancer.
