Abbreviations: CI=confidence interval; OR=odds ratio.
Multivariant analysis derived from Akaike's information criteria using a model comprising age at diagnosis, skin type (skin type 4 vs skin type 1–3), regular foreign holidays, childhood sunburn, average sunbathing score (never vs rarely/occasional/frequent) and average weekday and weekend exposures.
