In Reply: Dr Habib and colleagues suggest that
the hazard ratios we reported do not take into account differences in demographics
and comorbid conditions, and that we might have found different results had
we applied propensity modeling.
As we pointed out in our article, we calculated risk-adjusted hazard
ratios in our mortality analyses. This analysis accounted for a large number
of variables associated with demographics, comorbid conditions, and disease-specific
severity. We also conducted a propensity modeling analysis, although using
an approach different from that used by Koch et al,1 as
well as an analysis in which we stratified outcome comparisons by anatomical
risk. Our conclusion that women have poorer outcomes than men, particularly
early after revascularization procedures, was persistent across various analysis
