TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['We evaluated the effects of epidural injection with levobupivacaine or serum physiologic, epidural volume extension (EVE), when using combined spinal-epidural anesthesia (CSEA) for cesarean delivery.', 'One-hundred and thirty-eight patients with a full-term pregnancy of 37-42 weeks that were scheduled for cesarean delivery were included. Group 1 (n=48) received single-shot spinal anesthesia (SSS), group 2 (n=45) received CSEA-EVE with saline, group 3 received CSEA-EVE with levobupivacaine. The characteristics of motor and sensory block, the effects on maternal hemodynamic changes and the effects on the newborn were compared.', 'Time to reach maximum sensory block was significantly shorter in groups 3 than in group 1 and 2 (p<0.05). Two-segment regression time of sensory block was significantly shorter in group 1, whereas it was significantly longer in group 3 than in group 2 (p<0.05). Time to onset of motor block was significantly longer in group 1 than in groups 2 and 3 (p<0.05). Time to reach maximum motor block was significantly shorter in group 3 than in groups 1 and 2 (p<0.05). Time to recovery of motor block was significantly longer in group 3 than in groups 1 and 2 (p<0.05). The time to first analgesic was significantly longer in group 3 (p<0.05).'] Does combined spinal-epidural anesthesia with epidural volume extension cause a higher level of block than single-shot spinal anesthesia?
OUTPUT:

agent
yes
