Postprandial glucagon-like peptide 1 secretion is associated with urinary albumin excretion in newly diagnosed type 2 diabetes patients

Figure 1 Mean concentrations of glucose and some related endocrine hormones during the standard meal test. A: Glucose; B: Insulin; C: Glucagon; D: Glucagon-like peptide 1 (active). Values show means with standard error, ^aP < 0.05; ^bP < 0.01. GLP-1: Glucagon-like peptide 1.

Figure 2 Scatter plot the correlation between natural logarithm of urinary albumin-to-creatinine ratio and postprandial glucagon-like peptide 1 levels. A: Scatter plot for the correlations between 30 min glucagon-like peptide 1 (GLP-1) levels and the urinary albumin-creatinine ratio (UACR) in all type 2 diabetes mellitus (T2DM) patients; B: Scatter plot for the correlations between 120 min GLP-1 levels and the UACR in all T2DM patients; C: Scatter plot for the correlations between area under the curve for GLP-1 and the UACR in all T2DM patients. GLP-1: Glucagon-like peptide 1; UACR: Urinary albumin-creatinine ratio; AUCGLP-1: Area under the curve for active glucagon-like peptide 1; LnUACR: Natural logarithm of urinary albumin-to-creatinine ratio.
