*Chi-square.
†Odds ratio (OR) adjusted for age, sex, income, urbanization, HIV and transplant.
‡Urbanization levels in Taiwan are divided into four strata according to publications of the Taiwan National Health Research Institute; level 1 indicates the most urbanized areas, and level 4 indicates the least urbanized areas.
§DM: diabetes mellitus; HIV: human immunodeficiency virus infection; transplant: operation of transplant; ESRD: end stage renal disease; HTN: hypertension; CHC: chronic hepatitis and cirrhosis.
