Multivariate analysis (logistic regression analysis) for the factors that elevate serum CGA level in patients with pNET
| Factor | Parameter estimate | R | P-value | Odds ratio (95% confidence interval) |
|---|---|---|---|---|
| PPI use | 1.5144 | 0.16 | 0.038* | 4.55 (1.09–18.94) |
| Tumor classification | 0.5106 | 0 | 0.159 | 1.67 (0.82–3.39) |
| Liver metastasis | 2.8367 | 0.39 | 0.0001* | 17.06 (4.28–68.02) |
P-value was calculated using 2 × 2 χ2-test or Fisher's exact test.
