| Gender (F/M) | 264/205 | 73/73 | NS |
| Endoscopic diagnosis (year; n(F/M)) | |||
| Gastritis | |||
| - without intestinal metaplasia | 44.3; 209 (137/72) | 41.2; 31 (18/13) | NS |
| - with intestinal metaplasia | 54.5; 39 (29/10) | 57.0; 28 (22/6) | NS |
| Duodenal ulcer | 48.0; 131 (68/63) | 46.6; 31 (14/17) | NS |

* Either the age or the gender was matched between the 146 selected patients and the entire patients in each sampled groups (Pearson chi-square test for gender & Student's t test for age analysis).
