Parameter	Group 1 (n = 37)	Group 2 (n = 38)	Group 3 (n = 40)	P Value
FBS, mg/dL	175.3 ± 54.3	190.3 ± 57.2	226.2 ± 42.1	0.08
HbA1C	6.5 ± 0.6	7.1 ± 1.6	7.6 ± 0.5	0.13
Urine Alb/Cr	16.1 ± 5.8	136.2 ± 69.5	546.8 ± 141.1	0.001
Diabetes mellitus duration, y	5.2 ± 2.9	8.2 ± 2.3	12.3 ± 3.2	0.02

^a There were no significant differences between diabetic patients groups regarding fasting blood sugar (FBS) and HbA1C (P > 0.05). However, there were significant differences between the groups regarding random urine Alb/Cr (P = 0.001) and diabetes mellitus duration (P = 0.02).
