Association between in-hospital mortality and qSOFA calculated within 8 hours before ICU admission in patients with suspected infection. a Distribution of included patients according to number of qSOFA criteria met and corresponding mortality rates (p < 0.001 using chi-square test). b Comparison of the area under the receiver operating characteristic curves of qSOFA and SIRS criteria for in-hospital mortality (p = 0.03 using the Hanley and McNeil method). Abbreviations: qSOFA quick Sequential (Sepsis-related) Organ Failure Assessment, SIRS Systemic Inflammatory Response Syndrome, ICU intensive care unit
