Figure 4. Receiver Operating Characteristic Curves for Quick Sequential (Sepsis-Related) Organ Failure Assessment (qSOFA) Score or Systemic Inflammatory Response Syndrome (SIRS) Criteria Added to Baseline Risk Model for Hospital Mortality Among Patients With Suspected Infection in the Combined Cohort.

Baseline risk determined based on age, sex, HIV status, and transfer status. The area under the receiver operating characteristic curve (AUROC) data derive from the baseline model alone, baseline model plus qSOFA score (range, 0-3), and baseline model plus SIRS criteria (range, 0-4). AUROCs: baseline risk model, 0.56 (95% CI, 0.53-0.58); baseline risk plus qSOFA, 0.70 (95% CI, 0.68-0.72); and baseline risk plus SIRS, 0.59 (95% CI, 0.57-0.62).
