- The First Affiliated Hospital of Zhejiang Chinese Medical University
- Brief Summary
The purpose of this study is to assess the impact of multilevel factors on the quality of screening colonoscopy, reflected mainly by adenoma detection rate (ADR).
- Detailed Description

Multilevel factors, including patient-, proceduralist-, and procedure-level characteristics were analyzed for the relationship with ADR.
