a Providers and Specialists represent the total number of providers and number of specialists, respectively, seen by each person in the period.
b Degree is the count of all providers that share patients with the patient’s main provider.
c For each pair of providers on the patient’s team, we calculated the proportion of each providers’ patients who were shared with the other provider in the dyad in the previous period. Shared patient volume is the geometric mean all pairwise proportions.
d Six months ending at the time period indicated (relative to diagnosis date).
