From: Intrathecal dexmedetomidine as an adjuvant to plain ropivacaine for spinal anesthesia during cesarean section: a prospective, double-blinded, randomized trial for ED50 determination using an up-down sequential allocation method

Fig. 2

Individual response to intrathecal dexmedetomidine coadministered with ropivacaine at the corresponding dose (µg). The ED50 of intrathecal dexmedetomidine coadministered with ropivacaine for cesarean section was 5.9 µg (95% CI, 4.9 to 7.4 µg) in Group Rop8 and 3.1 µg (95% CI, 0.1 to 4.8 µg) in Group Rop10 using probit regression. An effective intrathecal block is denoted by a filled circle, while an ineffective block is denoted by an open circle. Dashed lines indicate the position of the estimates of ED50
