  • NOTE: Buttocks, genital area, and scalp not included. Surface of selected body areas represent 86.5% of total body surface area.

  • * No unadjusted ratio reached statistical significance.

  • Mean adjusted difference between males and females, with females being the reference category, expressed in %, and 95% confidence interval. % differences are derived from coefficients of a Poisson regression models, including variables related to sun exposure, the skin phototype, the eye color, the average number of holiday periods, the average total duration of sun exposure, the average difference in latitude, the number of sunburn episodes, the study place, the average wearing of trousers and shirt, the average wearing of hat, and the average sunscreen use during holidays.

  • Same model as for nevi 2 to 4.9 mm, with inclusion of numbers of nevi 2 to 4.9 mm as a continuous variable.
