Penalized Multivariable Regression Predictors for ARC

Characteristic	OR (95% CI)
Charlson Comorbidity Index	0.80 (0.16–1)
Major Trauma	1.75 (1–16.59)
Intracerebral Hemorrhage	2.82 (1–69.1)
Age	0.94 (0.83–1)
SOFA Score (ICU Admit)	0.99 (0.52–1)

ARC score = 1.07 – 0.22*Charlson Comorbidity Index + 0.56*Major trauma + 1.04*Intracerebral hemorrhage – 0.07*Age – 0.01*SOFA

ARC Probability = e^{ARC score}/(1 + e^{ARC score})
