Markers of the redox status in the erythrocytes: (A) GSH levels, (B) catalase (CAT) activity and plasma (C) TBARS, (D) CARBS and (E) TAC of patients with non melanoma skin cancer (NMSC) and non-NMSC (normal controls with UV-induced lesions and actinic keratosis) and their association with vitamin D levels (VDD: vitamin D deficiency, VDI: vitamin D insufficiency and VDS: vitamin D sufficiency). * p-values of 0.05 or smaller were considered statistically significant using a one-way ANOVA followed by post hoc multiple two-group comparisons (A–D) or a Kruskal–Wallis test (E).
