The incidence of UGIB in pre- and postintervention groups. That of preintervention group was 4%. The noninferiority margin was set at 10%; therefore, 4% + 10% = 14% was the predefined line. The incidence of UGIB in postintervention group was 4% [95% CI, 0.5–13.7%]. This upper limit of 95% CI (13.7%) was lower than the predefined line (14%).UGIB, upper gastrointestinal bleeding; CI, confidence interval
