  1. Medians [interquartile range], number (%) and means (standard deviation) reported, as appropriate. IP, individualized protocol; CP, conservative protocol; BMI, body mass index; RR, respiratory rate; EtCO2, end-tidal carbon dioxide; EtSevo, end-tidal sevoflurane concentration; IQR, interquartile range; SD, standard deviation. Time to fentanyl test was defined as the time from the start of anesthesia induction to the performance of the fentanyl test
