Is there a difference in adenoma detection rates between gastroenterologists and surgeons?

	Gastroenterologists (n = 150)	Colorectal surgeons (n = 150)	P-value
Female (%)	50.67	52	0.817
Patient age (mean, yr)	66.59	67.18	0.61
1st degree relative with CRC (%)	6.67	10	0.296
1st colonoscopy (%)	98	89.33	0.002
Trainee involved (%)	12	36.67	< 0.0001
Caecal intubation rate (%)	100	100	-
TI intubation rate (%)	70	36	< 0.0001
