extracted. One thousand datasets were generated using this method, each with the same
number of subjects as the original dataset.

Estimates of sensitivity and specificity were then calculated across datasets by taking the median
value. The confidence limits were generated from the 2.5

th

and 97.5

th

percentiles. This resulted

in the following estimates (

Sensitivity and specificity analysis was performed following an analysis rule of 2 of 3 consecutive observations of a SEM

delta of 0.6 or above (“SEM positive”) or SEM delta

less than 0.6

(“SEM negative”) from a five

-day window from study exit

or when a pressure ulcer is identified by visual skin assessment. This analysis rule was defined before study analysis was
performed.
