How effective are the components of active management of the third stage of labor?

Table 5 Predicted probability of post-partum blood loss ≥ 700 mL by AMTSL components and route of oxytocin administration

	Predicted probability
No oxytocin prophylaxis
No AMTSL components	8.8%
UM only	9.9%
CCT only	4.8%
UM + CCT	13.7%
Oxytocin prophylaxis
Intramuscular administration
Oxytocin only	3.9%
Oxytocin + CCT	1.3%
Oxytocin + CCT + UM	2.6%
Intravenous administration
Oxytocin only	1.0%
Oxytocin + CCT	1.1%
Oxytocin + CCT + UM	3.1%

Predictions were generated from regression models summarized in Table 4. They reflect the average probability of post-partum blood loss ≥700mL, assuming that all study participants in each clinical regimen received each AMTSL treatment but otherwise retained their observed characteristics.
