*3.3. Association between Vitamin and Mineral Concentrations and Histological Damage (Marsh-Classification)*

Table 4 depicts the mean serum vitamin and mineral values by Marsh strata. No statistically significant differences were found between the serum vitamin and mineral concentrations across the four Marsh strata, except for ferritin. Serum ferritin values decreased when the villous atrophy score increased (*p* = 0.041).
