Circulating adiponectin (ADPN) concentrations are decreased in patients with the metabolic syndrome (MS) in relation with increased oxidative stress and inflammation. Total and multimeric adiponectin (a), leptin (b), ADPN/leptin ratio (c), thiobarbituric acid reactive substances (TBARS, d), C-reactive protein (CRP, e), serum amyloid A (SAA, f) and osteopontin (OPN, g) concentrations in subjects with or without the MS. Box represents interquartile range and median inside, with whiskers showing 10/90 percentile. Differences between groups were analyzed by two-tailed unpaired Student’s t tests. *P < 0.05, **P < 0.01 and ***P < 0.001 for with MS vs without MS. CRP and SAA were logarithmically transformed due to non-normal distribution.
