Nagelkerke R2 = .498, χ2value= 576.69, p < .0001. The odds of developing MCI in female T2DM patients was 1.52 times the odds of males. The odds of developing MCI in T2DM patients of age group 41-60 years was 3.58 times whereas the odds of developing MCI in T2DM patients of age group > 60 years was 9.92 times compared to <40 age group. The odds of developing MCI in T2DM patients with HbA1c levels > 7.51 levels was 1.72 times, duration of T2DM >20 years was 2.04 times and educational qualification of 5-9 years and 10-14 years were 46.12 times and 4.21 times respectively.
