a
Timely PORT indicates no later than 42 days after surgery.
b
Frequency may not total numbers in column headings owing to missing or unknown values. Percentages have been rounded and may not total 100. Three patients were other races.
c
Because the reference group contains a cell with 0 count, the OR and 95% CI cannot be accurately estimated.
