Binary logistic regression analysis of predictors for poor functional outcome (mRS 3-6) at 3 months.

	OR (95% CI)	p
25(OH)D deficiency (<10 ng/mL)	1.86 (1.10–3.14)	0.021
Model 1	1.74 (1.01–2.97)	0.044
Model 2	3.01 (1.16–7.84)	0.024
Model 3	3.18 (1.21–8.36)	0.019
Model 4	3.21 (1.22–8.48)	0.019

mRS, modified Rankin Scale; OR, odds ratio; CI, confidence interval; 25(OH)D, 25-hydroxyvitamin D. Model 1 was adjusted for age and sex. Model 2 included variables in model 1 plus NIHSS and NIHSS^*25-hydroxyvitamin D deficiency interaction term. Model 3 included variables in model 2 plus stroke subtype (TOAST classification) and intravenous thrombolysis. Model 4 included variables in model 3 plus blood urea nitrogen, white blood cell count, and hemoglobin.
