Data are presented as number, %, unless otherwise specified. Percentages were calculated with outcomes as denominator.
Abbreviation: ICU, intensive care unit.
a P values based on χ2, Fisher exact test, or analysis of variance where appropriate.
b When the source of infection was documented as deriving from the abdomen by the primary treating physician.
c Clinical factor not included in multivariate analysis due to low number of outcomes or as other clinical factors considered more cogent without overfitting model.
