| Placental location | Posterior | Anterior | Non-central | ||
|---|---|---|---|---|---|
| P | OR(95%CI) | P | OR(95%CI) | ||
| Non-adjusted model | - | < 0.001 | 5.34(2.58,11.06) | < 0.001 | 5.53(3.19,9.06) |
| Model I | - | < 0.001 | 4.14(1.88,9.09) | 0.001 | 2.88(1.57,5.27) |
| Model II | - | 0.001 | 4.13(1.84,9.24) | 0.001 | 2.90(1.55,5.45) |
Non-adjusted model adjust for: None
