¹The dichotomous caecal intubation 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 caecal intubation was achieved in each sedation type and gender group.
