Fig. 3From: Serum metabolomics profiling by proton nuclear magnetic resonance spectroscopy reveals sexual dimorphism and masculinization of intermediate metabolism in women with polycystic ovary syndrome (PCOS)Proton nuclear magnetic resonance spectroscopy metabolomics profiling of carbohydrates, short-chain fatty acids, ketone bodies, and glycerol, as a function of group of subjects, obesity, and their interaction. Data are arbitrary units and are expressed as means ± SEM. Green symbols are control women; orange symbols are people with PCOS; and red symbols are control men. Squares are non-obese subjects and circles are obese people. *p < 0.05, **p < 0.01 and ***p < 0.001 for the differences among groups of subjects regardless of obesity; ‡p < 0.05, ‡‡p < 0.01 and ‡‡‡p < 0.001 for the differences among non-obese and obese people, regardless of the group of subjects; §p < 0.05, §§p < 0.01 and §§§p < 0.001 for the interaction between obesity and group of subjectsBack to article page
