Multivariable logistic regression analysis with backward elimination of factors independently associated with a unfavorable 90-day outcome

Independent variable OR (95% CI) P-value
Atrial fibrillation 2.51 (1.03–6.33) 0.049
Infarct volume (per mL) 1.03 (1.01–1.06) 0.005
Admission NIHSS (per point) 1.17 (1.08–1.28) <0.001
Pre-admission mRS (per step) 2.58 (1.66–4.01) <0.001

Hosmer-Lemeshow statistics (χ2 =7.862, p=0.447). The CHA2DS2-VASc score was not retained in this model. Results were identical when the individual components of the CHA2DS2-VASc score were entered.
