  1. Note: “*” Adjusted for age, sputum smear results by using two-level mixed-effects survival model
  2. “†” Adjusted for age, sputum smear results and years. The estimate of variance in level 2 was 0.32 with the standard error of 0.45. An LR test comparing the model with the one-level survival model didn’t favor the random-intercept model with P > 0.05
