The results indicated a significant predictive power of BMI percentile on inflammatory markers: IL-6 (AUC = 0.803, 95% CI: 0.72–0.88, p < 0.001), ICAM (AUC = 0.806, 95% CI: 0.72–0.89, p < 0.001) and endotoxemia (AUC = 0.762, 95% CI: 0.68–0.85, p = 0.019) (Table 3, Figure 2a,b). The gene discussed is IL6; the disease is serum lipopolysaccharide activity.
