Comparison of distribution for (A) peak pressure and (B) average of the highest 4 pressures between pressure ulcer (PU) and no pressure ulcer (No-PU) outcome groups. The difference in mean was significant (p ≤.01) in both cases. Box plots show the minimum, maximum, upper quartile, lower quartile, mean (grey line), and median (solid line) for each data set.
