Abbreviations correspond to 12 nursing assessments of table 1, plus creatinine and heart rate. Also included is age as a possible confounding factor. All pairs have low R-squared coefficients of determination, indicating that every variable could contribute to the model's goodness of fit (for ranking the categories of discharge disposition).
