Association between dietary iron intakes and quality of life measured with EuroQol index in UC patients with quiescent disease (closed triangles and full black line) and matched ‘healthy’ controls (open circles and dashed black line). A, total dietary iron; B, haem iron; C, non-haem iron; D, fortificant iron. There were no significant slope deviations from zero (linear regression) for both UC patients and matched controls (p>0.05, n=34 per group).

Linear association between quality of life measured with the McMaster IBDQ and the generic EuroQol EQ-5D-5L. A, EQ VAS, EuroQuol Visual Analogue Scale score; B, EQ index value. The best-fit line is shown with the 95% confidence band and the p-value for the linear associations: n=48.
