Fig. (2) Correlation of IP-10 and sCD14 with viral loads and CD4 counts. Spearman’s correlation coefficient was used to determine strength of association between biomarkers (log10 IP-10 and log10 sCD14) and markers of disease progression (log10 viral loads and CD4 counts). Log10 IP-10 levels positively correlate with log10 viral load (A) and negatively with CD4 count (B). CD14 levels were not significantly associated with neither log10 viral load (C) nor CD4 count (D).
