Brief summary

We aimed to develop a predictive model of inadequate bowel preparation and to further validate it by a randomized controlled trial.

Interventions

DRUGPolyethylene Glycol

In the Tailored group, high-risk people are given intensified bowel preparation regimens, low-risk people are given routine regimens. In the control group, all the patients are given routine regimens.
