Table 1 Diagnostic odds ratios of endoscopic findings in the diagnosis of three groups of Helicobacter pylori infection status

Endoscopic finding	H. pylori
	Uninfected	Infected	Eradicated
RAC	11.5 (3.73-35.1)	0.03 (0.00-0.14)^a	1.65 (0.61-4.47)^a
Linear erythema	24.5¹ (4.12-146)	0.05¹ (0.00-0.83)^a	0.18 (0.00-1.20)^a
Hemorrhage	4.11 (1.54-11.0)	0.03 (0.00-0.19)^a	2.52 (0.92-6.95)^a
Fundic gland polyp	34.5¹ (1.89-632)	0.10¹ (0.01-1.81)^a	0.15¹ (0.01-2.81)^a
Atrophic change	0.01 (0.00-0.06)	8.67¹ (2.11-35.6)^a	32.4¹ (1.87-562)^a
Rugal hyperplasia	0.02¹ (0.00-0.34)	15.8 (4.86-51.4)^a	0.66 (0.22-2.03)
Edema	0.10 (0.03-0.31)	14.2 (4.52-44.1)^a	0.66 (0.24-1.81)
Spotty erythema	0.09 (0.00-0.60)	11.5 (3.03-42.7)^a	0.35 (0.00-1.54)
Exudate	0.27 (0.00-1.18)	3.52 (1.16-11.6)^a	0.77 (0.21-2.93)
Xanthoma	0.86 (0.22-3.46)	2.45 (0.64-9.29)	0.30 (0.00-2.02)
Mottled patchy erythema	0.07¹ (0.00-1.17)	0.07¹ (0.00-1.17)	103¹ (5.64-1888)^a

Values of odds ratios (95%CI) are shown.

¹Odds ratios were estimated using the substitution formula. 0.5 was added to all cell frequencies before calculation.

^aP < 0.05 vs uninfected. RAC: Regular arrangement of collecting venules; H. pylori: Helicobacter pylori.

Hemorrhage	0.79
Fundic gland polyp	0.93
Atrophic change	0.74
Rugal hyperplasia	0.49
Edema	0.58
Spotty erythema	0.47
Exudate	0.46
Xanthoma	0.19
Mottled patchy erythema	0.75

RAC: Regular arrangement of collecting venules.
