In model 1 (crude model), the odds ratio(OR) of GNRI (continuous variable) for poor outcome was 0.891 (95% CIs, 0.865–0.918, P < 0.01), and in multivariate model 3, which adjusted for age, sex, drinking, smoking, the infarct type, comorbidity, thrombolytic therapy, CRP, BMI, and NIHSS, the OR of GNRI (continuous variable) for outcome was 0.885 (95% CIs, 0.855–0.917) (P < 0.01). This evidence concerns the gene CRP and infarction.
