disease category

Figure 1. hscTnT level (ng/L) linearly predicted outcome. The multivariable logistic regression model was adjusted for Acute Illness
Severity Score, Comorbidity Score, and Sepsis status. Increasing hscTnT level predicted 30-day in-hospital mortality (calculated on per
admission episode or on unique patient basis) derived from and plotted based on the model prediction. hscTnT: high-sensitivity cardiac
troponin
