Effect of vitamin D on CDAI and IBDQ scores. (a) CDAI scores were decreased significantly after vitamin D₃ supplementation for 24 weeks. (b) Beginning and ending CDAI for each patient are connected by a line. All but one patient had a lower CDAI score at the end of the study than at the beginning. Horizontal dashed lines indicate the CDAI score of 150 that indicates remission. (c) IBDQ scores increased significantly after vitamin D₃ supplementation for either 12 weeks or 24 weeks. (d) The beginning and ending IBDQ scores are connected by a line. Most (15 of 18) of the participants showed improvement in the IBDQ scores following vitamin D₃ supplementation. Horizontal dashed line is at 170, which is the threshold indicating poor quality of life.
