External Validation of Models for Predicting Inadequate Bowel Preparation

In order to obtain the risk level of patients with intestinal insufficiency through simple indicators, many foreign scholars have studied and developed their own prediction models. However, the current guideline indicates that there is insufficient evidence to recommend the use of a specialized predictive model for clinical practice.There are few studies on external validation of existing prediction models.
