  1. Summary of intraclass correlation coefficients (ICCs) of the Academic Medical Center Linear Disability Score (ALDS) and the Short Form 12 (SF-12) physical component score (PCS) and mental component score (MCS) summary scores between patients and their proxies for all patients, for all ICU patients, for ICU scheduled admissions, for ICU emergency admissions and for coronary care unit (CCU) patients separately. CI, confidence interval.
