Table 2: Incidence and adjusted odds ratios for clinical outcomes. While the incidences of clinical outcomes were not significantly different, after adjusting for confounders, No/Yes patients had significantly increased vasospasm but decreased poor discharge characteristics. Incidences considered statistically significant if p ≤ 0.05. *Adjusted OR statistically significant according to 95% confidence intervals. No/No: No beta blockade. No/Yes: Post-admission beta blockade only. Yes/Yes: Preadmission and post-admission beta blockade. CI: confidence interval.
