VAS scores for appetite and upper gastrointestinal symptom scores
fullness, upper gastrointestinal symptoms
UPPER GASTROINTESTINAL SYMPTOMS
The paper-based VAS was made up of a 100 mm line anchored at each end with positive and negative extremes for each of the appetite variables (hunger, fullness, satisfaction, desire to eat and prospective food consumption). Without reference to previous ratings, participants instructed the research nurse to mark a vertical line across the horizontal 100 mm line, and the metric value (mm) was measured from the 0 mm (on the left) to the vertical mark.The characterisation of the upper gastrointestinal symptoms scores was reported on a VAS of 0–100 mm, with absence of symptoms = 0 and very severe symptoms = 100 at each end, in conjunction with a pictorial representation of symptoms and verbal description
