a nonsignificant trendP = 0.200
A nonsignificant trend toward a shorter duration in drug to extubation (MD: 0.31, 95% CI [−0.17, 0.78], P = 0.200), operating room discharge (MD: 0.28, 95% CI [−0.24, 0.80], P = 0.290), PACU entry (MD: 0.12, 95% CI [−0.37, 0.60], P = 0.640), and PACU stay (MD: 0.31, 95% CI [−0.96, 1.58], P = 0.630) was observed in the PtDA group compared with the classical group ( Table 4 ).
