Mean EQ-5D index and VAS scores by RESQ-7 Heartburn domain frequency (a) and severity (b) at 6 months’ follow-up. For both EQ-5D scores, 0 represents a health state of being dead and 1 a health state of being at full health (VAS scores were re-scaled from 0–100 to 0–1 for purposes of comparison). Frequency and severity of symptoms were based on the item within the domain with the highest frequency. The relationship between symptoms and EQ-5D results is described at the 6-month assessment, since the number of patients in each symptom category was most evenly distributed at this time point.
