  1. ¶ Proportional hazard assumption is valid in all univariate and the multivariable Cox proportional hazard models.
  2. Ф Adjusting for Sex, Age, CD4 count category and WHO stage. Occupation was not included in the multivariable model because it was not significant in the univariate analysis; neither does it change the model significantly.
