Comparative study of therapeutic effects of PPI and H2RA on ulcers during continuous aspirin therapy

Figure 1 Gastroduodenal ulcer healing was endoscopically achieved in proton pump inhibitors and histamine 2 receptor antagonists group patients. A: Gastroduodenal ulcer healing was endoscopically achieved in 88.5% of proton pump inhibitors (PPI) group patients and in 84.6% of histamine 2 receptor antagonists (H2RA) group patients. There was no significant difference between the two groups; B: Gastroduodenal ulcer healing in patients with non-pangastritis was endoscopically achieved in 88.2% of PPI group and in 86.7% of H2RA group. There was no significant difference between the two groups. NS: Not significant.
