Adjusted odds ratios between occupational exposure to ultraviolet radiation (UVR) and basal cell carcinoma (BCC), and modifying effects by skin complexion.

aTotal number of participants varies due to missing data for some covariates;
bAdjusted odds ratios (95% CI) for sex, age, county of residence, family history of cancer, skin complexion, and lifetime average arsenic concentration in drinking water;
cAny UVR consists of natural UV, artificial UV, and both (results omitted due to scarce data); associations were estimated in two separate multivariable logistic regression models;
dCumulative lifetime exposure is not showed for artificial UVR because of small numbers per strata;
*Significance of the Wald Chi-Square test for interaction at p<0.10.
