Admission duration waterfall plot.

The total number of admissions in the patient database is shown, followed by the number removed due to a missing value for the classifier, leaving the number of admissions included in the analysis at day 1. On each day, bars show the number of patients discharged alive (light blue) or deceased (dark blue). The numbers above the bars represent the total number of patients remaining on intensive care at the start of the day and the percentage that this represents of all admissions included in the analysis, for days 1, 5, 10, 20 and 30. Where a total is shown, the grey bar represents those remaining on ICU at the end of the day.
