aComparison between historical overall and COVID groups
bComparison between historical minus OAR and COVID groups
cP values across all Clavien-Dindo classes (1 to 4)
dThe sum of individual complications is greater than the total number of patients with complications since some individuals had more than one complication
eIncluding blood product transfusion, mesh infection, bacteremia, enterocutaneous fistula, pleural effusion, acute urinary retention, high ileostomy output, ostomy outlet obstruction, septic shock, medication-induced rash
