aRecycled prediction method; The following outcome models had questionable fit due to estimated G matrix not positive definite: all-cause readmission at 30, 60, and 90 days; pneumonia; infection
bDischarge to a non-home setting (e.g., skilled nursing facility, intermediate care facility) vs. discharge to home with or without home healthcare
cIn minutes; n with operating room time data = 538 powered; 2190 manual; operating room time values trimmed to fall between 30 min and 24 h
