  1. The table showed the mean, median and 2.5th -97.5th percentile values of the absolute CD4 counts and percentages form the adult Indian population. The region wise and gender wise values of CD4 counts and percentages have been given. The absolute CD4 counts and percentages form female and male participants were compared using the Mann Whitney's non parametric t test and found to be significantly higher in female participants.
  2. *: The reference ranges as shown by 2.5th -97.5th percentile have been mentioned in bold.
