Association of Helicobacter pylori infection with insulin resistance, tumor necrosis factor-alpha, and dyslipidemia in obese children with metabolic syndrome

Figure 3 Receiver operating characteristic curves of homeostasis model assessment of insulin resistance and tumor necrosis factor-alpha for discrimination of Helicobacter pylori infection. Homeostasis model assessment of insulin resistance demonstrated excellent discrimination [area under the curve (AUC) = 0.954], while tumor necrosis factor-alpha showed moderate discrimination (AUC = 0.677). The diagonal dashed line represents non-discrimination. HOMA-IR: Homeostasis model assessment of insulin resistance; AUC: Area under the curve; TNF-α: Tumor necrosis factor-alpha.
