Table 2 Associations between hospital infections and recovery in the original dataset and the imputed dataset

	OR recovery	95% CI	p-value
Original Data. crude analysis	0.76	0.61–0.96	0.018
Imputed Data. crude analysis	0.75	0.59–0.95	0.017
Imputed Data. weighted* analysis	0.79	0.60–1.03	0.077

*Weights based on inverse of the propensity score for infection risk. The propensity score model included 13 variables: baseline PHS, unstable angina pectoris, age, gender, extra-cardiac arteriopathy, chronic lung disease, critical preoperative state, diabetes, NYHA Class III or IV, LVEF, recent myocardial infarction, urgency and surgery on thoracic aorta
