Satisfaction assessment
COMPLICATIONS
After the colonoscopy, the subjects completed a questionnaire to assess the satisfaction of laxative preparations using a 10-point numeric rating scale from 0 (very bad) to 10 (excellent). Acceptance was graded as none, some, or much difficulty in taking the study agent. Compliance was graded as optimal, defined as 100% intake of study agent; good, defined as ≥ 60% intake of study agent; and poor, defined as < 60% intake of study agent. When the inspectors assured that the subjects did not have any complications, they were able to return home under standardized care.
