Results are from multivariable linear mixed effects models. Slope estimate presented is for the average slope among all patients following the given number of admissions. As a result of the model specification, change in slope following ICU admission is the same after each subsequent ICU admission and therefore only presented once in the table. P-values test whether the change in slope due to ICU admission is significantly different from 0.
