Recurrence, n (%)	1 (1.6)	0 (0.0)	1.000

Data are expressed as numbers (%) for the numeric parameters and as median (range) for the continuous parameters
Continuous variables were analyzed using the Mann–Whitney test, while categorical variables were analyzed using Fisher’s exact test
Statistical significance was set at P value < 0.05
A/T/D colon, Ascending/Transverse/Descending colon
^*The polyp volume was calculated using the ellipsoid volume equation (= 4/3πr₁r₂r₃)
^†The morphology of polyp is classified by Paris classification; Ip, pedunculated; Isp, semipedunculated; Is, sessile (23)
