Cumulative distribution of subepidermal moisture (SEM) is provided for each of three levels of visual skin assessment (VSA): no skin damage, mild skin damage (erythema or Stage 1 pressure ulcer), and more-severe skin damage (Stage 2+pressure ulcer). When evaluated at the 50% level for cumulative frequency according to VSA, SEM values are lowest when no skin damage is observed, followed by higher values for mild damage and highest values for severe damage.
