Exposure was defined as taking the medication continuously for more than 3 months per year, or taking the medication intermittently for more than 6 months per year.

Exposure was defined as taking the medication continuously for more than 3 months per year, or taking the medication intermittently for more than 6 months per year. According to the standardised use of TCM protocols, the group was divided into an exposed group (TCM protocols cohort) and a non-exposed group (non-TCM protocols cohort).
