Disability count by pre–intensive care unit (ICU) cognitive status over 6 months of follow-up (N = 266). The 266 ICU admissions were contributed by 215 participants who survived to their first post-ICU monthly interview. The disability counts range from 0 to 13. As a reference point, the pre-ICU disability count (from the month before ICU admission) is included at Month 0. The table presents the number of observations contributed by participants alive at each month of follow-up by pre-ICU cognitive status. There was no attrition for reasons other than death. MMSE = Mini-Mental State Examination.
