PDR, polyp, polyps, NRS, adenomas
SECONDARY, PMR, ADENOMAS
The primary outcome was AMR, the calculation was performed as follows:The secondary outcomes were ADR, PMR, polyp detection rate (PDR), insertion time (IT) and withdrawal time (WT).AMR, ADR, PMR, and PDR were calculated in each group, and then subgroup analysis was performed according to the characteristics of patients (age, gender, indications, type of laxatives, and time period of examination), the characteristics of colonoscopy procedures (cecal insertion distance, the length of cecum and ascending colon, IT, WT, QBP, NRS, polyps detected, and adenomas detected) and the characteristics of polyps (the first detected and missed polyps, the first detected and missed adenomas).(see Supplemental Digital Content B, Categorical data are presented as number and percentage and compared by
