Association between hospital volume and observed to expected (O/E) ratio. This scatterplot illustrates the distribution of hospitals based on the (O/E) ratios for the Hospital Composite Indicators, QI1, and Outcome Indicators. x-axis: represents the O/E ratio, where a value of less than 1 indicates better-than-expected performance, and a value of greater than 1 indicates poorer-than-expected performance. y-axis: represents the number of cases in a hospital. Red Dot: Hospitals with O/E ratios less than 1 are categorized in the "poorer performance group," indicating that these hospitals are performing worse than expected. Blue Dot: Hospitals with O/E ratios greater than 1 are categorized in the "Better Performing Group," indicating that these hospitals are performing better than expected.
