Table 3.
Logistic regression models including gastric cancer or first-degree relative of gastric cancer patients as variables dependent in comparison with gastritis and oipA, age and gender as independent variables
| Variables | Univariate | Multivariate | ||
|---|---|---|---|---|
| P value | OR | 95% CI | P value | |
| Gastric cancera | ||||
| Increasing age | 0.06 | 1.08 | 1.03–1.14 | 0.003 |
| Gender | 0.74 | |||
| oipA + status “on” | 0.013 | 9.20 | 1.45–58.48 | 0.02 |
| Relatives of GCb | ||||
| Increasing age | 0.70 | – | – | – |
| Gender | 0.09 | 4.61 | 1.22–17.74 | 0.02 |
| oipA + status “on” | 0.003 | 14.75 | 2.53–86.13 | 0.003 |
+, positive; OR, odds ratio; CI, confidence interval; Relatives of GC, first-degree relatives of gastric cancer patients. The Hosmer-Lemeshow tests showed good fitness of the logistic regression model a(P = 0.46; 8 degrees of freedom; 9 steps) and b(P = 0.42; 8 degrees of freedom; 9 steps)
