Multiple analyses confirm the association of serum 25(OH)D concentration with Breslow thickness of primary melanomas.

Additional statistical tests, including gender and time of blood draw in multiple analyses, confirmed our finding that serum 25(OH)D concentrations are associated with Breslow thickness of primary melanomas (n = 307; 17 Patients were excluded from this cohort due to missing clinical data). Considering Breslow thickness of primary melanomas as dependent and gender, season of blood draw as well as serum 25(OH)D concentration as independent variables, the adjusted serum 25(OH)D concentration effect resulted in a p-value of 0.013.Multiple analyses confirm the association of serum 25(OH)D concentration with Breslow thickness of primary melanomas.
