  1. Data are presented as mean (SD), median (IQR), or n (%).
  2. #The standardized mean differences between patients with and without virologic rebound after weighting were presented.
  3. *Initial decline: The first 2 samples showing initial decline in Ct values. To avoid transient dynamics of Ct values within a day, the Ct values were summarized as their mean value if a patient had multiple Ct measurements on the same day.
  4. **The date of virologic rebound occurring was defined as the date of initial decline of 3 units in the Ct value.
  5. VR virologic rebound, SMD standardized mean difference, Ct cycle threshold.
