APOA1 and type 2 diabetes mellitus: Ultimately, the five variables of Neutrophil (OR = 0.908, 95% CI (0.870, 0.945), p < 0.001); 25(OH)D3 (OR = 0.877, 95% CI (0.863, 0.891), p = 0.001); Duration of T2DM (OR = 1.167, 95% CI (1.134, 1.210), p < 0.001); HbA1c (OR = 1.172, 95% CI (1.094, 1.213), p < 0.001); and ApoA1 (OR = 1.806, 95% CI (1.311, 2.492), p < 0.001) were statistically significant and hence selected for the development of the prediction model (Table 2).
