| Clinical case characteristics | Number of Studies | Heterogeneity test results | Effect model | Meta-analysis results | ||
|---|---|---|---|---|---|---|
| I2 (%) | P | OR (95% CI) | P | |||
| Number of metastases | 8 | 10 | 0.35 | Fixed-effects model | 1 (0.76–1.31) | P = 0.97 |
| CEA | 6 | 46 | 0.1 | Fixed-effects model | 1.31 (0.88–1.96) | P = 0.19 |
