¹In 10 instances the endoscopist reported “ulcer number” as “multiple”. Therefore the total number of ulcers is unknown and percentages cannot be calculated;

²Cases where H. pylori was absent from ulcer margin, but had either positive rapid urease test, positive C13-urea breath test or positive histology in biopsy not taken from ulcer margin. NSAID: Non-steroidal anti-inflammatory drugs; H. pylori: Helicobacter pylori; IM: Intestinal metaplasia. +: Positive; -: Negative.
