| Variable | Multivariable analysis (before PSM) | Multivariable analysis (after PSM) | ||
| OR (95% CI) | P value | OR (95% CI) | P value | |
| Any portion of liver in chest: (ref.: no) | 5.473 (1.483 to 20.207) | 0.011 | 10.451 (1.641 to 66.544) | 0.013* |
| Gestational week at diagnosis (per week) | 0.763 (0.647 to 0.899) | 0.001* | 0.736 (0.577 to 0.938) | 0.013* |
*P<0.05 was considered statistically significant.
PSM, propensity score matching.
