The Operative Link on Gastritis/Intestinal Metaplasia (OLGIM) and (Operative Link on Gastritis Assessment (OLGA) classifications tools were used for identifying participants at high risk for gastric cancer by evaluating the severity and extent of &lt;em&gt;H. pylori&lt;/em&gt; infection and IM.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;The study found that IM and &lt;em&gt;H. pylori&lt;/em&gt; prevalence were gender-related, with males representing 41.09 % of cases compared to 33.92 % of controls, a significant difference (&lt;em&gt;P&lt;/em&gt; &lt; 0.0001). Conversely, females were more prevalent in the control group (66.07 %) compared to the case group (58.91 %).

IM showed significant positive correlations with smoking , alcohol consumption , and drinking water sources . &lt;em&gt;H. pylori&lt;/em&gt; infection was detected in 238 (10.81 %) of the case group and 542 (11.07 %) of the control group. Using the OLGIM classification, which incorporates IM into gastric cancer risk assessment, stage 0 (no IM) was observed in 1,189 (24.28 %) of the control group and 530 (24.09 %) of the case group. Stage 1 (mild IM) was found in 3,165 (64.62 %) of the controls and 1,432 (65.09 %) of the cases. Stage 2 (moderate IM) was present in 520 (10.62 %) of the controls and 220 (10 %) of the cases, while stage 3 (severe IM) was observed in 24 (0.49 %) of the controls and 18 (0.82 %) of the cases. For OLGA staging, the case group had a higher percentage of individuals in higher stages (III and IV) compared to the control group. Specifically, 50.84 % of the cases were classified as stage 0, 19.75 % , stage I, 14.71 %, stage II, 8.40 %, stage III, and IV, 6.30 %.
