† Only analyzed patient with severe intoxicated or admitted to the hospitals.
‡ Adjusted model were adjusted with year of hospital visit, sex, socioeconomic status, history of diabetes, hypertension, history of ischemic heart disease or heart failure, cerebrovascular disease, obstructive lung diseases, chronic kidney disease, liver disease, psychiatric illness, history of malignancy, and previous intoxicated events in the prior year.
§ Bonforroni method was used to correct for multiple comparison between different age group. We reported adjusted CI after Bonforroni correction.
*p < 0.05
