Figure 3. Ketoprofen improves skin thickness and cutaneous pathology in placebo-controlled study.

(A) For the placebo-controlled trial, pre- and posttreatment skin thickness were measured for the ketoprofen (n = 14) and placebo groups (n = 15). (B) Violin plots of the changes in the blindly assessed histopathology scores. The change (Δ) represents the value of the posttreatment minus the pretreatment score.
