Logistic regression analysis of association between high pro-brain natriuretic peptide and demographic variables
| Demographic variables | Univariable analysis |
| OR (95% CI) | |
| Age, per 5 years | 1.22 (0.95 to 1.56) |
| Charlson Comorbidity Index, point | 1.32 (0.97 to 1.80) |
| Initial shockable rhythm, yes | 1.92 (0.43 to 8.69) |
| Time to ROSC, per 5 min | 1.10 (0.89 to 1.37) |
| Lactate concentration at admission, per mmol/L | 0.90 (0.77 to 1.05) |
| Circulatory shock* in the ER, yes | 0.53 (0.14 to 1.96) |
*Systolic blood pressure <90 mmHg or in need of fluids and/or vasopressors to maintain systolic blood pressure >90 mmHg.
ER, emergency room; ROSC, return of spontaneous circulation.
