Table 4 3DVs/3DVg and progesterone for early adverse pregnancy

	ROC	Cut-off	Sensibility	Specificity	Positive predictive value	Negative predictive value
3DVs/3DVg	0.767 (0.691, 0.844)	0.220	0.702	0.750	0.625	0.809
Progesterone	0.649 (0.557, 0.741)	18.2	0.677	0.625	0.756	0.530
3DVs/3DVg combined progesterone	0.824 (0.756, 0.891)	0.664	0.770	0.821	0.881	0.676

3DVs: Three-dimensional volume of subchorionic hematoma; 3DVg: Three-dimensional volume of GS; ROC: Receiver operating characteristic.
