*, denotes significant difference (P=0.003) between the audited periods; **, denotes significant difference (P=0.008) between the audited periods; ***, denotes significant difference (P<0.0001) between the audited periods. N, number of colonoscopies; SAR, sedation administration rate; CI, confidence interval; CCR, colonoscopy completion rate; ADR, adenoma detection rate; CR, early complications rate.
