Note: The analysis was performed by using multivariate Cox proportional hazard regression model. The predictors which exhibited significant differences between survivors and non-survivors at 12-month follow-up (shown in Table 1) were put into the multivariate Cox proportional hazard regression for analysis, with an elimination criterion of p >0.05, to investigate their regression coefficient, adjusted hazard ratio, and p-values. Abbreviations: ACEI = angiotensin-converting enzyme inhibitors, aHR = adjusted hazard ratio, ARB = angiotensin receptor blocker, B = Cox regression coefficient, CI = confidence interval, CPR = cardiopulmonary resuscitation.
