Figure 2: Distribution of patients and 28-day mortality by qSOFA score, lactate concentration, and qSOFA-lactate score in the derivation cohort Bars show distribution of patients (blue bars) and 28-day mortality (red bars) by qSOFA score (A), lactate concentration (B), or qSOFA-lactate score (C). Error bars show 95% CIs for 28-day mortality. qSOFA=quick Sequential Organ Failure Assessment.
