Between-hospital standard deviation of mean mortality rate	.078	(.077, .080)	.079	(.076, .083)
Mean annual change in mortality rate	−.007	(−.009, −.006)	−.007	(−.009, −.006)
Within-hospital standard deviation of annual change in mortality rate	.137	(.132, .143)	.135	(.128, .142)
Between-hospital standard deviation of annual change in mortality rate	.031	(.029, .032)	.030	(.027, .032)
Mean sample size	104.8	(100.7, 109.0)	105.1	(101.5, 109.0)

Note. Centers for Medicare and Medicaid Services (CMS) moment conditions are calculated using inpatient data from 2002 to 2006.
