Predicted risk of death and readmission at 24 hour intervals in up to the last four days in the ICU.

aDay 0 = predictions generated at the time of ICU discharge; Day 1 = predictions generated 24 hours prior to discharge; Day 2 = predictions generated 48 hours prior to discharge; Day 3 = predictions generated 72 hours prior to discharge. bThe average change in predicted risk (%) across the last four ICU days using linear regression with a robust variance estimator clustered by patient across ICU days. c600,252 observations. d9,830 observations. e40,801 observations. All p-values <0.01.
