Relationship between individual cytokine levels. Paired cytokine values were plotted for IP-10 vs. IL-1Ra (A), IL-18 vs. IL-1Ra (B), and IL-18 vs. IP-10 (C). Comparisons were stratified by Negative infection (LEFT), Positive infection but seronegative (MIDDLE), and Positive infection and seropositive (RIGHT) status. Pearson correlation analysis and linear regression were performed on log2-scaled cytokine values. CIs are represented by shaded region (95% CI 0.80-0.97).
