*
Adjusted model includes adjustment for the following 3 covariates based imbalance before weighting: number of high risk diagnoses, presence of dyspnea, prior inpatient stay. Adjusted and PS weighted model findings are similar but variability in the PS weighted model is significantly reduced over the adjusted model.
