Figure 2
Temporal changes in uterine contractions after the start of magnesium sulfate treatment in the magnesium-alone group (a) and combination group (b). The dotted lines in the magnesium-alone group represent those who required reinfusion of ritodrine to inhibit uterine contraction. Asterisks represent those who delivered within 48 hours of magnesium infusion.
