Figure 1

Comparison of facility rankings by four methods. Method 1 (a) uses simple event counts per person, Method 2 (b) event rates per year of resident follow-up, Method 3 (c) statistical model of rates using four predictors, and Method 4 (d) the change in ranks between methods 2) and 3). The 10 facilities ranked the highest in a) are shown in yellow, and the 10 ranked highest in d) are shown in brown in all charts, to demonstrate variability between methods. One facility is shown as both yellow and brown.
