Higher age, WFNS, comorbidity, IVH, ICH, DCI-related infarction, and secondary respiratory failure were independent predictors of poor outcome, whereas NRT was not. In light smokers, NRT was a significant predictor of poor outcome in the univariate analysis (OR 2.926, 95% CI 1.220–7.020, p = 0.016) and borderline significant in the multivariate analysis (OR 3.245, 95% CI 0.911, 10.621, p = 0.052).
