Values of HBA1c, blood pressure, and creatinine (normally distributed) are expressed as mean (SD). Values of cholesterol, triglycerides, and HDL-cholesterol (non-normally distributed) are expressed as median (interquartile range). *A significant difference existed between groups 2 and 4 (p<0.0001); †a significant difference exists between groups 1 and 3 (p = 0.001), 1 and 4 (p<0.0001), and 2 and 4 (p = 0.015); ‡a significant difference was found between groups 1 and 4 (p = 0.036); §a significant difference exists between groups 1 and 3 (p<0.0001), 1 and 4 (p<0.0001), 2 and 3 (p<0.0001) and 2 and 4 (p<0.0001). NS, non-significant.
