The VIP plot showed AC2 (higher in women with MetS, regardless of age, and younger men with MetS diagnosis), ALT (higher in men with MetS, regardless of age, and younger women with MetS diagnosis), AC3 (higher in MetS groups, regardless of sex), UA (higher in men with MetS diagnosis regardless of age), and glycine (higher in women −MetS group, regardless of age) are suitable for discrimination between groups (Figure 5B). The gene discussed is GPT; the disease is metabolic syndrome.
