Interlimb volume difference represents the volume difference in the arm affected with BCRL and the arm that does not have BCRL; larger values indicate greater BCRL severity.
Lymphedema care adherence was based on the past 3 months and calculated as “no” if the respondent was not being prescribed any treatment or used prescribed treatment less than 25% of the time and “yes” if the respondent used prescribed treatment at least 25% of the time in the past 3 months.
