Definition of abbreviations: AUC = area under the receiver operating characteristic curve; CI = confidence interval; CSC = crisis standard of care; LAPS2 = version 2 of the Laboratory-based Acute Physiology Score; SOFA = Sequential Organ Failure Assessment.

Significant difference (P < 0.05) between white and Black patients for a given mortality prediction score.

^{^†}

SOFA score divided into four categories: <6, 6–8, 9–11, and ≥12.

^{^‡}

Significant difference (P < 0.05) compared with SOFA score among all patients.

^{^§}

One-half of a point subtracted from SOFA score if renal component of the SOFA score is >0 among Black patients.

^{^ǁ}

LAPS2 divided into eight categories: <40, 40–79.9, 80–119.9, 120–159.9, 160–199.9, 200–239.9, 240–279.9, and >280.
