aDue to incomplete data and branching logic, the total number of responses varies by question. The total number of complete responses per question is provided next to each response in-line. Percentages are based upon the number of responses out of the total number answering the question. Means and standard deviations are calculated using only complete responses. bRespondents are allowed to select more than one service, as many centers offer all or a combination of these services. cTo derive RDN-to-patient ratio. The analytic patient cases were divided by RDN FTEs individually for each center that provided both data points. One center reported having a RDN but no analytic cases (1 : 0). RDN = Registered Dietician Nutritionist; NCI = National Cancer Institute.
