2. Figure 1
ROC curves generated with PGI (gray line), PGII (black line), PG I:II (gray dashed line), and gastrin 17 (black dashed line) for detecting any kind of gastritis among first-degree relatives of gastric cancer patients. The area under the curve is 0.67 for PGI, 0.85 for PGII, 0.27 for PG I:II ratio, and 0.67 for gastrin 17.

3. Figure 2
ROC curves generated with PGI (gray line), PGII (black line), PG I:II (gray dashed line), and gastrin 17 (black dashed line) for detecting corpus-predominant gastritis among first-degree relatives of gastric cancer patients. The area under the curve is 0.47 for PGI, 0.65 for PGII, 0.28 for ratio, and 0.66 for gastrin 17.
