Table 3 Optimal cutoff value and predictive power of modified shock index and shock index for massive transfusion in primary postpartum hemorrhage.

	Cut-off	Se	Sp	PPV	NPV	PLR	NLR
Modified shock index	1.34	74.3	77.1	40.2	93.5	3.25	0.33
Shock index	1.07	68.6	83.2	45.9	92.7	4.09	0.38
Se – sensitivity; Sp – specificity; PPV – positive predictive value; NPV – negative predictive value; PLR – positive likelihood ratio; NLR – negative likelihood ratio.
