Carbonated soft drink for gastric preparation for magnetically controlled capsule endoscopy: An open-label randomized controlled trial

Figure 1 Schematic diagram of gastric filling score. A: Score 5. Smooth gastric mucosa without folds; B: Score 4. The height of mucosal folds was lower than the distance between the adjacent mucosal folds at greater gastric curvature; C: Score 3. The height of mucosal folds was roughly equivalent to the distance between the adjacent mucosal folds; D: Score 2. The height of mucosal folds is greater than the distance between the adjacent mucosal folds; E: Score 1. Gastric mucosa between folds was hard to observe.
