Improving long term outcome for diabetic patients undergoing surgical revascularization by use of the radial artery conduit: a propensity matched study.

However while their comparison of unmatched but risk adjusted groups failed to reach statistical significance (95% CI 0.36 -1.37; p= 0.29) our propensity matched comparison of larger RA and SV groups showed the 32% relative risk reduction achieved in our RA group to be highly statistically significant and therefore RA use in our series statistically predicts better survival (HR 0.683, CI 0.507- 0.920, p=0.0122).
