¹Odds ratio for Kyoto score 2 vs Kyoto scores 0 + 1.

²Odds ratio for Kyoto scores 1 + 2 vs Kyoto score 0.

³Odds ratio for regular arrangement of collecting venules presence vs absence.

Odds ratios were calculated per 1 rank of Kyoto score. H. pylori: Helicobacter pylori; GC: Gastric cancer; OR: Odds ratio; RAC: Regular arrangement of collecting venules.
