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

Figure 3 Comparison of Revised Faecal Incontinence Scale and Fecal Incontinence Quality of Life scores in patients with Crohn’s disease, with and without perianal fistula. A: Revised Faecal Incontinence Scale scores; B: Fecal Incontinence Quality of Life scores. Scoring key for RFIS (range 0-20): No fecal incontinence = 0 points, very mild ≤ 3 points, mild = 4-6 points, moderate = 7-12 points, severe ≥ 13 points; scores for each item were summed and the mean taken, with lower scores indicating less fecal incontinence. Scoring key for FIQL (range 1-5): Lower scores indicating lower health-related quality of life; the minimally important difference is 1.1-1.2 points per subscale. Numbers inside the bars present the number of patients. CD: Crohn’s disease; CPF: Crohn’s perianal fistulas; FIQL: Fecal Incontinence Quality of life; HRQoL: Health-related quality of life; PF: Perianal fistulas; RFIS: Revised Faecal Incontinence Scale.
