Change in Strength of Predictors. The percent change in β coefficients between the original 30-day model and the re-derived 7-day model is shown for each predictor included in the model. Predictors are grouped according to the timing of their availability, including baseline characteristics prior to the index hospitalization (red), factors on hospital admission (light blue), factors during hospital stay (gold) and factors on discharge day (dark blue). Values to the right of the vertical dashed line at 0, shown in striped color, indicate factors that are more predictive of early readmission. Values to the left of the dashed line showed in solid color, indicate factors that are less predictive. Variables that are still statistically significant in the 7-day model are denoted with an asterisk (*)
