Fig 1. Location of the index DFU.
A color-coded diagram was used by the DFC to indicate the location of the index DFU: Plantar forefoot (orange), plantar midfoot (yellow), heel (green), malleolus (purple), dorsum (blue) and toes (red). The number and proportion (%) of men and women with a DFU at a known location is indicated next to the respective color. The sum of percentages can exceed 100%, as a DFU can span multiple locations. The proportions of both groups were compared using generalized estimating equations.
