FIGURE 4.

A box-and-whisker plot demonstrating significant differences in (A) Staphylococcus aureus and (B) Acinetobacter baumannii CFUs between RX-4-NPWT–treated simple tissue wounds and all other wound management groups at 72 hours post–simulated flight (* above each group denotes significant differences between that group and RX-4-NPWT). There is also a significant difference in A. baumannii CFUs between WTD dressing and NS-NPWT at 72 hours post-flight in simple tissue wounds (median ± interquartile range). There were no differences noted between flight and ground groups, or ground groups compared to one another, although ground groups were not powered to detect statistical differences. * P < .05; ** P < .01; and *** P < .001.
