¹The dichotomous polyp detection dependent variable was regressed on the sedation type, age, and gender independent variables using binary logistic regression. Output is expressed as odds ratios and P values. 2This column lists the number (simple percentage) of patients in which polyp(s) was/were detected in each sedation type and gender group.
