Multiple analyses confirm that median serum 25(OH)D concentrations are significantly lower in melanoma patients as compared to controls.

Additional statistical tests, including age and time of blood draw (BMI data were not available) in multiple analyses and ANOVA, confirmed that median serum 25(OH)D concentrations are significantly lower in melanoma patients as compared to controls. Considering 25(OH)D as dependent and sex, age, season of blood draw as well as group as independent variables, the adjusted group effect resulted in a p-value of 0,012.Multiple analyses confirm that median serum 25(OH)D concentrations are significantly lower in melanoma patients as compared to controls.
