Sankey diagram comparison of group membership. Conventional groups (on the left): dry (continent), stress urinary incontinent, urgency urinary incontinent, mixed urinary incontinent, and other urinary incontinent are compared with four clusters identified in this paper (on the right). Each of conventional groups contributes members to each of the new clusters. “Dry” means continent, SUI-stress urinary incontinent, UUI- urge urinary incontinent, MUI- mixed urinary incontinent, OUI- other urinary incontinent.
