Correlation between OSDI total scores and age as well as disease duration in CD and UC patients. The continuous lines show the fitted curves, while the dotted lines represent the 95% confidence bands (obtained with linear regression in cases when there was a significant correlation between the data sets). (a) CD OSDI total score and CD age; (b) CD OSDI total score and CD disease duration; (c) UC OSDI total score and UC age; (d) UC OSDI total score and UC disease duration. OSDI: ocular surface disease index; CD: Crohn’s disease; UC: ulcerative colitis.
