	With trainees, n = 370	Without trainees, n = 968	P value	OR (95%CI)
Patient age, median (IQR)	64 (57-72)	64 (57-72)	0.83	-
Patient gender (male %)	53.5 (n = 198)	47.4 (n = 463)	0.06	-
Cancer detection rate (%)	4.1 (n = 15)	3.3 (n = 32)	0.51	1.24 (0.66-2.31)
CSPDR (%)	41.4 (n = 147)	42.7 (n = 400)	0.67	0.95 (0.74-1.21)
ADR (%)	38.9 (n = 138)	40.4 (n = 378)	0.62	0.94 (0.73-1.21)
