^a Patient percentage of each risk bin is defined as the percentage of patients in that bin of the total prospective population.

^b Mean resource utilization per person in each risk bin is defined as the next 6-month mean resource utilization per person in that bin.

^c Confidence level of each risk bin is defined as the proportion of patients in that bin with next 6-month resource utilization less than the estimated maximum resource utilization.
