Fig. 1.
Effect of diet and exercise intervention on serum concentration of the cytokines IL-8, IL-6, TNFα, IL-10, and IL-1 receptor antagonist (IL-1ra) in normal-weight (filled bars) and obese children (open bars). All data are expressed as means ± SE. ‡P < 0.01 and *P < 0.05, postintervention (post) vs. preintervention (pre). †P < 0.05, baseline differences between the normal-weight and obese groups. The baseline difference between normal-weight and obese group for IL-10 was P = 0.12.
