a

Reliability adjustment is an application of hierarchical modeling that uses empirical Bayes techniques to quantify and remove the statistical bias associated with small sample sizes.

b

P values compare across quartiles of reliability-adjusted rates.

c

Teaching hospital defined by New York State Department of Health using graduate medical education codes on Medicaid claims, verified by the Office of Primary Care and Health Systems Management and the Department of Education.
