On multivariate analysis (Table 3), FIB-4 score (OR 1.894, p = 0.011), history of atrial fibrillation (OR 3.488, p = 0.017), high admission NIHSS score (OR 1.305, p < 0.001) and low blood values of Hb (OR of high Hb levels OR 0.730, p < 0.001) remained significant predictors of poor prognosis. Here, GSTM1 is linked to atrial fibrillation.
