Mean ± SD serum 25(OH)D concentrations were compared with ordinal values in the Mayo endoscopy score, total Mayo score, and histologic score. P values were calculated with the use of the nonparametric trend test and represent the trend in serum 25(OH)D concentrations across ordinal values in the represented scoring index. 25(OH)D, 25-hydroxyvitamin D.
