Correction: Association of ulcerative colitis symptom severity and proctocolectomy with multidimensional patient-reported outcomes: a cross-sectional study(Journal of Gastroenterology, (2023), 58, (751–765), 10.1007/s00535-023-02005-7)

Abstract

Fig. 2h of the original article contained extraneous yellow data bars; Fig. 2h should appear as shown in this correction. (Figure presented.) Proportion of patients reporting a QOL as low, normal or high on SIBDQ; b severe fatigue on FACIT-F; c depression or d anxiety on the HADS scale; e absenteeism, f presenteeism, g work productivity, and h activity impairment on WPAI; and i poor sleep quality on PSQI. FACIT-F Functional Assessment of Chronic Illness Therapy – Fatigue, HADS Hospital Anxiety and Depression Scale, PSQI Pittsburgh Sleep Quality Index, QOL quality of life, SIBDQ Short Inflammatory Bowel Disease Questionnaire, WPAI Work Productivity and Activity Impairment In Fig. 3 of the original article, the labelling of ‘y’ axis was reversed (i.e., better/worse outcome); Fig. 3 should appear as shown in this correction. (Figure presented.) Associations of symptom severity and proctocolectomy with patient-reported outcomes. Data indicate SMD and their 95% confidence intervals. The fraction of variance of symptom severity explained by each outcome is shown in parentheses. The magnitude of the effect size was interpreted as: small, SMD = 0.2; medium, SMD = 0.5; and large, SMD = 0.8 [39]. Total number of patients included in the analysis were: SIBDQ (N = 1956), FACIT-F (N = 1935), HADS-D (N = 1958), HADS-A (N = 1958), WPAI-A (N = 1346), WPAI-P (N = 1346), WPAI-L (N = 1346), WPAI-I (N = 1909), and PSQI (N = 1917) (see Table 3 footnotes for breakdown by patient group). FACIT-F Functional Assessment of Chronic Illness Therapy – Fatigue, HADS Hospital Anxiety and Depression Scale (A, anxiety; D, depression), PSQI Pittsburgh Sleep Quality Index, SIBDQ Short Inflammatory Bowel Disease Questionnaire, SMD standardized mean difference, WPAI Work Productivity and Activity Impairment (A, absenteeism; I, impairment of activity; L, loss of productivity; P, presenteeism)
