Note: Per federal research regulations, data on patients who were unable to transfer and patients who were unable to ambulate are not reported, since some cell counts were ≤10. For the same reason, Asians and Blacks were collapsed into a “non-white” category. Data are presented as count (column %) or mean (± standard deviation), unless indicated otherwise.
Abbreviations: AFib – atrial fibrillation; ESRD – end-stage renal disease
