Fisher's exact test;
2
Age-adjusted for sex; sex-adjusted for age;
3
Multivariable-adjusted OR in stepwise logistic regression model, where age and sex were forced to enter into the model; other significant factors were selected from history of abdominal or pelvis surgery, poor bowel preparation, and inflammatory bowel disease with P < 0.05 for entry and removal. -: Not entered into the model to avoid multicollinearity; NS: Not selected.
