Logistic Regression Model of Composite Outcome^* during Heparin Contamination.

SE indicates standard error; OR, odds ratio; CI, confidence interval; CH, contaminated heparin; #, number of comorbidities; LVEF, left ventricular ejection fraction; CPB, cardiopulmonary bypass time; TXA, tranexamic acid. Overall fit: 2 Log likelihood ratio = 65.9, P<0.0001; Wald F = 5.8 on 12 and 906 degrees of freedom, P<0.0001; Hosmer-Lemeshow: X2 = 4.9, Degrees of freedom = 8, P = 0.87. *Composite outcome is any postoperative myocardial infarction, stroke, pneumonia, dialysis or cardiac arrest.
