Baseline characteristics of the NACURG cohort.

Differences between patients who died and those who survived were assessed by Cox regression survival analysis for independent continuous variables, and a Kaplan-Meyer survival curve with log-rank tests for independent categorical variables. Differences between patients with or without adverse event were assessed by the Student t test or the non-parametric Mann-Whitney U test for continuous variables and the [χ2] test or the Fisher exact test for dichotomous categorical variables. *p: degree of statistical significance. **Lactate levels only available for 122 patients (54%) and not therefore included in the multivariate analysis. ***The percentage of readmissions out of the total number of patients discharged (221; 4 patients died while in hospital and 1 was still inpatient at 30 days). Relationship between different independent variables and adverse event and 90-day mortality after consulting the Emergency Department.
