Logistic multivariable regression of risk factors of overall mortality
| Variable | Multivariable analysis (before PSM） | Multivariable analysis (after PSM） | ||
| OR (95% CI) | P value | OR (95% CI) | P value | |
| EXIT (ref. non-EXIT） | 0.234 (0.062 to 0.883） | 0.032* | 0.083 (0.013 to 0.525） | 0.008* |
| Any portion of liver in chest: (ref.: no) | 5.609 (1.626 to 19.348) | 0.006* | 16.955 (2.342 to 122.767) | 0.005* |
| Gestational week at diagnosis (per week) | 0.782 (0.686 to 0.89) | <0.001* | 0.662 (0.497 to 0.881) | 0.005* |
*P<0.05 was considered statistically significant.
EXIT, ex utero intrapartum therapy; PSM, propensity score matching.
