Significant relationship were observed between diabetic nephropathy and age of patients [p<0.005], type II diabetes [p<0.003], duration of diabetes [p<0.003], fasting blood sugar [p<0.008] and kind of anti-diabetic drugs [p<0.003], but there was not a relationship between gender and diabetic nephropathy [p=0.345].
