Increased fasting plasma GLP-1 levels are correlated with increased fasting plasma glucose, HbA1c and plasma triglyceride levels. Plasma triglyceride levels were significantly increased in diabetic patients, as compared to non-diabetics (a). There was a significant positive correlation between plasma GLP-1 and plasma triglycerides (b, c); this positive correlation was also detected in diabetic patients (d). Fasting plasma GLP-1 showed an inverse relationship to fasting plasma glucose (e) and HbA1c (f) in diabetic patients. *p < 0.05; **p < 0.01; ***p < 0.001 compared with non-diabetic subjects. Comparisons between groups were made using an unpaired t-test. Significant correlations were assessed using the Pearson correlation coefficient
