Figure 2 The serum levels of hepatocyte growth factor (HGF) (A) were significantly correlated with body mass index (BMI) as determined by linear regression analysis. To maintain the scale of the graph, three obese patients with HGF concentrations in the 4,000 to 6,500 pg/ml range are omitted from this graph. However, they are included in the statistical analysis. Circulating vascular endothelial growth factor (VEGF) levels (B), on the other hand, were not correlated with the degree of obesity. A value of p > 0.05 was considered not significant (NS). Open squares = lean subjects; solid circles = obese subjects.
