Figure 7.

Kaplan–Meier plot showing the likelihood (survival probability) of wound closure in wounds treated with nitric oxide gas (gNO)‐producing probiotic patches versus wounds treated with vehicle control patches. These data show that gNO‐producing probiotic patch‐treated wounds closed before wounds treated with vehicle control patches (log‐rank P = 0·0223 and Wilcoxon P = 0·011) and that several non treated wounds remained open. The light grey line is gNO‐producing probiotic patch‐treated wounds (16 wounds) and the dark grey line represents vehicle control‐treated wounds (16 wounds). These data were graphed using EpiInfo software (Center for Disease Control).
