 Optimal remission cut offs for the non-invasive indices are sensitive and specific. The cut offs were chosen to optimise sensitivity and specificity for remission. For the simple clinical colitis activity index (SCCAI) (A), this cut off was <2.5 points, resulting in a sensitivity of 0.79 and a specificity of 0.82. For the Seo index (B), this cut off was <120 points, resulting in a sensitivity of 0.96 and a specificity of 0.82. For the inflammatory bowel disease quality of life index (IBDQ) (C), this cut off was ⩾ 205 points, resulting in a sensitivity of 0.81 and a specificity of 0.82.
