*P < 0.05. HR, hazard ratio; CI, confidence interval. Hazard ratios were calculated with the stratified Cox proportional regression method (stratified by sex, age group, and the year of index health care use) during the 3-year follow-up period. Adjustments were made for Charlson Comorbidity Index in the patients.
