<qa>  What was the size of the esophageal varices measured in?To reflect practice in the real world, the endoscopic procedures were deliberately chosen to be carried out by regularly scheduled endoscopists rather than a small selected group of very experienced endoscopists. Varices were regarded as present or absent, with size recorded as either large 5 mm diameter or small 5 mm diameter based on subjective assessment of diameter.. Titrated sedation was undertaken in all patients with midazolam and fentanyl.. The size of the esophageal varices was measured in the distal 5 cm of the esophagus during withdrawal of the instrument.
