Error bars from the hospital-level random effects are shown at 1.4 times the standard error, indicating that two hospitals have significantly different performance if their error bars do not overlap. Hospitals are ranked by performance. The range of adjusted mortality among hospitals was 10.9%–13.3% for quintile 1, 13.4%–14.4% for quintile 2, 14.5%–15.0% for quintile 3, 15.0%–16.2% for quintile 4, and 16.2%–20.7% for quintile 5.
