Quarterly PCI Attempts by Decile of DES Utilization
A hierarchical multivariable logistic regression model with quarterly DES utilization rate as the main effect of interest was developed to determine the adjusted rate of PCI attempted during the DES era at each hospital site (p = 0.036). The Y-axis is the PCI attempt rate in patients with a class I indication for coronary artery bypass grafting. The X-axis is the mean quarterly DES utilization rate by center.
