Task: Answer Verification
Input (English): Question: Is twin vaginal delivery associated with lower umbilical arterial blood pH of the second twin and less intrapartum blood loss?
Answer: Twin vaginal deliveries were associated with slightly but significantly lower UmA-pH of the second twin, whereas twin cesarean delivery was associated with significantly larger intrapartum blood loss. Not only the neonatal risk but also the maternal risk should be taken into account when an optimal delivery mode for the twin pregnancy is considered.
Output (English): yes
