Multivariate logistic regression analysis to determine which variables are predictive of 28-day mortality in 169 patients ≥ 18 years of age admitted to the emergency intensive care unit with shock.

Variable	OR (95% CI)	Statistical significance
Lactate levels 24 h after EICU admission	–	NS
APACHE II score on EICU admission	–	NS
cf-DNA on EICU admission	–	NS
cf-DNA after 24 h in the EICU	–	NS
cf-DNA change over 48 h	4.232 (1.547, 11.579)	P = 0.005

OR, odds ratio; CI, confidence interval; EICU, emergency intensive care unit; APACHE II, Acute Physiology and Chronic Health Evaluation; cf-DNA; cell-free DNA.

NS, not statistically significant (P > 0.05).
