Percent AK clearance at week 8 after treatment. (a) The reduction in AK counts on combined anatomical sites and each anatomical site after calcipotriol plus 5-FU versus Vaseline plus 5-FU treatment. Average clearance percentages were compared between treatment groups for subjects who had 4–10 AKs on an anatomical site at baseline. (b) The reduction in hypertrophic AK on the face after calcipotriol plus 5-FU (n = 13) versus Vaseline plus 5-FU treatment (n = 20). ∗∗∗∗P < 0.0001, ∗∗∗P = 0.0002, and ∗∗P = 0.002. 5-FU, 5-fluorouracil; AK, actinic keratosis.
