Colonic vitamin D receptor expression is inversely associated with disease activity and jumonji domain-containing 3 in active ulcerative colitis

Figure 2 Vitamin D status in healthy controls and ulcerative colitis patients and its relationship with disease activity, age and duration of disease. A: Serum levels of vitamin D in control and ulcerative colitis (UC) patients (control: 56; UC 100; mild activity: 29; moderate activity: 32; severe activity: 39); B: Serum vitamin D levels in smokers (13.5 ± 2.7 ng/mL, n = 40) and non-smokers (13. 8 ± 2.9 ng/mL, n = 60); C: Serum vitamin D levels in patients receiving steroids (13.3 ± 3.3 ng/mL, n = 31) and non-steroids (13.8 ± 2.6 ng/mL, n = 69); D: Correlation between vitamin D level and the Mayo score in patients with UC; E: Correlation between vitamin D level and age in patients with UC; F: Correlation between vitamin D level and duration of disease in patients with UC. ^bP < 0.01 and ^cP < 0.001.
