As septic patients show high mortality rates, timely risk prediction and stratification are crucial to initiating early, aggressive, and effective treatment in this high-risk patient collective [1]. Several risk scores, including Sequential Organ Failure Assessment (SOFA) and Simplified Acute Physiology Score (SAPS), have been developed to predict outcomes in these patients [2,3]. However, as these scores are complicated and time-consuming to calculate, their use in initial risk prediction seems not rational.
