J Pak Inst Med Sci Jan ;7(1):458-60.

A study was carried out to determine the relation of the koebner response to age of onset in patients with psoriasis. In all, SO psoriatic patients were questioned. It was found out that the average age of onset or psoriasis of patients who reported the koebner phenomenon was fourteen years less than the average age or onset of psoriasis of patients who did not report the koebner response.
