  1. Time-dependent Cox regression models, CD8 CD4 ratio, PLR, NLR were considered at enrolment and every year. The observational period were divided into intervals of 1 year duration
  2. Abbreviations: HR hazard ratio, 95% CI 95% confidence interval, PLR platelet to lymphocyte ratio, NLR neutrophil to lymphocyte ratio
