CD4 and infection: Interestingly, there was significant association between intrapatient viral diversity at one year post infection with both viral load set point (Spearman’s correlation, r = 0.48 and p = 0.02) (Fig. 2E) and viral load at one year (Spearman’s correlation, r = 0.53 and p = 0.01) (Fig. 2F) but no significant association between the CD4 count and intrapatient diversity at 1 year (Spearman’s correlation, r = −0.23 and p = 0.31) (data not shown).
