VEGFA and type 2 diabetes mellitus: After applying the backward elimination method of the logistic regression, the following significant preoperative risk factors for developing NVG entered the multivariable model: more prolonged duration of T2DM (OR 1.132, 95%CI 1.018-1.260, p=0.023), preoperatively increased IOP (OR 1.192, 95%CI 1.019-1.395, p=0.029), increased levels of VEGF (OR 1.002, 95%CI 1.000-1.003, p=0.002), operative complications (OR 0.234, 95%CI 0.055-0.992, p=0.049), and intraoperative sharp dissection (OR 0.114, 95%CI 0.024-0.534, p=0.006) (Table 3).
