  1. *Per ideal body weight: mean daily prescription dose (mg)/ideal body weight (kg), which was calculated from the most recently measured height before the initiation of HCQ prescription during the baseline period.
  2. **Per actual body weight: mean daily prescription dose (mg)/actual body weight (kg); which was the most recently measured actual body weight prior to the initiation of HCQ prescription during the baseline period.
  3. The mean daily dose was calculated from the total HCQ prescription dose on the HCQ prescription days.
  4. HCQ hydroxychloroquine.
