Multi-national observational study to assess quality of life and treatment preferences in patients with Crohn’s perianal fistulas

Figure 2 Comparison of Short Inflammatory Bowel Disease Questionnaire scores and Quality of Life in patients with Anal Fistula scores in patients with Crohn’s disease, with and without perianal fistula. A: Short Inflammatory Bowel Disease Questionnaire (SIBDQ) scores; B: Quality of Life in patients with Anal Fistula scores. Scoring key for SIBDQ (range 1-7): Poor health-related quality of life (HRQoL) = 1 point and optimum HRQoL = 7 points. Scoring key for QoLAF (range 14-70): Zero impact = 14 points, limited impact = 15-28 points, moderate impact = 29-42 points, high impact = 43-56 points, very high impact = 57-70 points. CD: Crohn’s disease; CPF: Crohn’s perianal fistulas; HRQoL: Health-related quality of life; PF: Perianal fistulas; QoLAF: Quality of Life in patients with Anal Fistula; SE: Standard error; SIBDQ: Short Inflammatory Bowel Disease Questionnaire.
