Note: Network measures for each ICD capable physician and the average, 1^st, and 3^rd quartile of all physicians in the ICD hub networks are shown. Physicians A, B, and C are from St. Mary Medical Center (83.5% evidence-based ICD implantation) and Physicians H and I are from the Memorial Hospital (58% evidence-based ICD-implantation).
