* Abbreviations: CI, Confidence Interval; ICU, Intensive Care Unit; APACHE, Acute Physiology and Chronic Health Evaluation

Age, APACHE II Score, Charlson Co-morbidity Index and Education are all continuous variables. ADLs were measured at 1-month post-ICU discharge.

R² = 0.26 for Physical Component and R² = 0.28 for Mental Component

Adjusted R² = 0.17 for Physical Component and Adjusted R² = 0.20 for Mental Component
