Table 3.

Stratified logistic regression analysis to identify relationships between serum magnesium levels and risk of hemorrhagic transformation after thrombolysis.

	OR (95% CI)	P
Serum magnesium, per 0.1-mmol/L increase
< median (<0.85 mmol/L)	0.33 (0.12–0.93)	0.037
≥median (≥ 0.85 mmol/L)	0.58 (0.14–2.51)	0.47

The model was adjusted for the same confounding factors as in model 1 in Table 2.

CI, Confidence interval; OR, Odds ratio.
