From these sources, we propensity score matched 430 women with heart failure who received a primary prevention ICD to 430 women who did not; we further adjusted using a Cox proportional hazards model. Median follow-up was 3.4 and 3.0 years. For comparison, we matched 859 men receiving an ICD with 859 who did not; median follow-up was 3.9 versus 2.9 years. In the matched cohorts, an ICD was associated with similarly better survival in women (hazard ratio, 0.78; 95% confidence interval, 0.66\u20130.92;\n              <jats:italic>P<\/jats:italic>\n              =0.003) and men (hazard ratio, 0.76; 95% confidence interval, 0.67\u20130.87\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001).
