Figure 1 Provider variation in unadjusted total cost. Median unadjusted total cost (circles) and associated confidence interval (diamonds), as estimated by the random effects model, are presented for each provider. The overall median is represented by the solid line. Data points and labels of outlier providers are outlined with rectangles.

Figure 3 Provider variation in adjusted total cost. Median adjusted total cost (circles) and associated confidence interval (diamonds), as estimated by the mixed effects model, are presented for each provider. The overall median is represented by the solid line. No outlier providers were identified. For reference, data points of outlier providers identified in the unadjusted analysis are outlined with rectangles.

Figure 4 Provider variation in adjusted catheterization cost. Median adjusted catheterization cost (circles) and associated confidence interval (diamonds), as estimated by the mixed effects model, are presented for each provider. The overall median is represented by the solid line. Data points and labels of outlier providers are outlined with ovals. For reference, data points of outlier providers identified in the unadjusted analysis are outlined with rectangles.
