RBC indicates red blood cell; WBC, white blood cell; BC, buffy coat.
Used in the analysis of postoperative bacterial infection after patient exclusions and withdrawals.
In both the treatment and control arms combined.
Investigators making diagnoses of postoperative infection were blinded to the treatment allocations.
