CXCL10 and infection: Mean IP-10 levels at baseline were lower in patients who achieved RVR than in those who did not (RVR: 240±26 pg/mL vs 492±100 pg/mL, P = 0.024) (Figure 3a) with similar results seen restricting the analysis to those with genotype 1 infection (RVR: 230±41 pg/mL vs 560±140 pg/mL, P = 0.033) (Figure 4a).
