What researchers measure

Primary outcomes

  1. Recurrence rate of gastric or duodenal ulcer within 24 weeks

    Mucosal defects with a white coating of 3 mm or larger will be determined as ulcers. Recurrence rate of gastric or duodenal ulcer within 24 weeks will be calculated for each treatment group.

    Time frame: 24 weeks

Secondary outcomes

  1. Recurrence rate of gastric or duodenal ulcer within 12 weeks

    Time frame: 12 weeks

  2. Gastric mucosal injury

    Time frame: 24 Weeks

  3. Duodenal mucosal injury

    Time frame: 24 weeks

  4. Occurrence rate of hemorrhagic lesion in stomach or duodenum

    Time frame: 24 weeks

  5. Time to recurrence of gastric or duodenal ulcer

    Time frame: 24 weeks
