Figure 2

A Serum amylase levels according to plasma leptin levels. Subjects were divided into three groups based on leptin levels: normal (< 25 pg/ml), moderate (25–35 pg/ml), and high (> 35 pg/ml). The number of subjects in each group is shown under the bar. *Statistically significant difference between moderate and high leptin (Bonferroni’s test, P = 0.013). Bars represent standard errors. B Serum amylase levels according to leptin and obesity. Subjects were divided into three groups as in Figure 2A and then into lean (BMI<25 kg/m2) and obese (BMI ≥ 25 kg/m2) groups. The number of subjects in each group is shown under the bar. Leptin levels were significantly different between the lean and obese groups (two-way ANOVA, P = 0.02). §Statistically significant difference between lean and obese subjects in the normal and moderate leptin groups (Mann–Whitney test, both P<0.05). Bars represent standard errors. C HOMA-R according to leptin and obesity. Subjects were divided as in Figure 2A and B. The number of subjects in each group is shown under the bar. HOMA-R was significantly different between lean and obese subjects in the high leptin group (Mann–Whitney test, P = 0.004). Bars represent standard errors. D Leptin according to the leptin and obesity. Subjects were divided as in Figure 2A and B. The number of subjects in each group is shown under the bar. Bars represent standard errors.
