Re-Epithelialization Score and Dermal Inflammation Score

(A) Re-epithelialization mean scores and SD by study arm. Numbers (n) of independent histological samples evaluated for epithelialization score are indicated. Significantly higher re-epithelialization score was found in the high-dose (PCB × 3) arm relative to both the PTA control and nominal-dose (PCB × 1) arms, although no significant differences were found between any arms at 28 days post-treatment (Mann-Whitney test). (B) Dermal inflammation mean scores and SD by study arm. Numbers (n) of independent histological samples evaluated for inflammation score indicated. Significantly lower inflammation score was found in the PCB × 3 arm relative to both the PTA control and PCB × 1 arms, although no significant differences were found between any arms at 28 days post-treatment (Mann-Whitney test). Abbreviations as in Figure 1.
