CI, confidence interval; IABP, intra-aortic balloon pump; ICU, intensive care unit; IQR: interquartile range; MOF, multiorgan failure; MV, mechanical ventilation; Reference for the events: Mechanical valve cohort. § Least squares regression for continuous dependent variables has been expressed as standard regression coefficient, standard error, and p value.
