  1. Data are mean ± standard deviation or count.
  2. aPatient subgroups are the followings: Subgroup 1 = patients living close to the center and having the desired in-person visit number; Subgroup 2 = patients living close to the center and having less in-person visits than desired; Subgroup 3 = patients living far from the center and having the desired in-person visit number; and Subgroup 4 = patients living far from the center and having less in-person visits than desired.
  3. bBased on data of the whole study population (n = 161) and 27, 6, 74, and 54 patients in subgroups 1, 2, 3, and 4, respectively.
  4. cA total of 86 patients had a follow-up period of 5 years, while data of 17, 8, 36, and 25 patients could be analyzed in subgroups 1, 2, 3, and 4, respectively, for the 5-year follow-up.
  5. NA = not applicable.
