Associations between serum superoxide dismutase (SOD) levels at baseline and cognitive impairment after stroke.

	Model 1	Model 2	Model 3
	OR (95% CI)	OR (95% CI)	OR (95% CI)
CI-E: MoCA within 2 weeks
Per 1 SD increased in SOD	0.62 (0.46–0.87)	0.62 (0.42–0.91)	0.64 (0.42–0.99)
P-value	0.005	0.013	0.045
CI-L: MoCA at 3 months
Per 1 SD increased in SOD	0.52 (0.33–0.82)	0.34 (0.17–0.69)	0.33 (0.16–0.72)
P-value	0.005	0.003	0.005

Model 1: unadjusted.

Model 2: adjusted for age; sex; education; history of smoking; drinking; hypertension; diabetes; stroke and hyperlipidemia; stroke causes; NIHSS score; Barthel index; BMI; infarcted location.

Model 3: adjusted for the factors above, plus WBC; ESR; IL-6 and CRP.

1 SD = 23.0 U/ml.
