  2. *p-value <.001
  3. aIncidence is presented as 1000 person-year (PY)
  4. bAge, gender, geolocation, insurance level, comorbidities, medications, and previous TCM experience, were adjusted in the Cox regression model to evaluate the adjusted hazard ratio (aHR) for all-cause mortality. Age, gender, geolocation, insured level, comorbidities, medications, previous experience with TCM were fitted in the competing-risk regression to evaluate the adjusted cause-specific hazard ratio (aCSHR) for ESRD
