Figure 7

Linear regression analysis of relationships between body weight or weight loss with various circulating hormones or postprandial hormone responses. Correlations included either all treatment groups (lean controls, open triangles; sham-operated obese, open circles; RYGB, filled circles; full regression lines) or only RYGB rats (dotted regression lines), and only significant correlations are shown. A and B, Leptin levels are positively correlated to body weight and negatively to body weight loss using all treatment groups. C and D, Areas under the curve (AUC) for GLP-1 and PYY are negatively correlated to body weight across all treatment groups and for RYGB rats only. E and F, AUC for amylin and percent suppression of acylated ghrelin are positively correlated with body weight loss. G, GLP-1 and PYY AUCs are positively correlated. H, Twenty-minute peaks of GLP-1 and insulin are positively correlated. I, Basal insulin is positively correlated with body weight. J, HOMA-IR is negatively correlated with body weight loss.
