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

Figure 1 Serum tumor necrosis factor-alpha levels by Helicobacter pylori infection status among obese children with a metabolic syndrome phenotype. Box plots depict the median (center line), interquartile range (box), and whiskers (1.5 × interquartile range), with individual participant values overlaid. Tumor necrosis factor-alpha levels were significantly higher in the Helicobacter pylori (H. pylori)-positive group compared with the H. pylori-negative group (Mann-Whitney U test, P = 0.011). H. pylori: Helicobacter pylori; TNF-α: Tumor necrosis factor-alpha.
