of at least 75%, but the rather small size of the sample
probably explains the absence of statistical significance.
Interestingly, localization seems to be clearly associatedwith the response to treatment, whereas factors such as
age, sex, skin type, and minimal erythemal dose are not.
When adjustment is made for localization, combinationtreatment is clearly superior to laser monotherapy when
treating UV-resistant areas, confirming our initial hy-
pothesis. On the other hand, no statistical difference can
be found between the 2 treatments when treating UV-sensitive areas. For technical reasons, it was impossible
to also evaluate the efficiency of tacrolimus ointment alone
