Figure legends
Figure 1 . Adjusted dose-response relationship between propofol requirement and age. Adjusted for gender, BMI, albumin, bilirubin, ALT, AST, and GFR. BMI, body mass index; ALT, alanine aminotransferase; AST, aspartate aminotransferase; GFR, glomerular filtration rate.
Figure 2 . The changes of hemodynamic parameters at 5 different time points during the induction of anesthesia. (A ) Mean arterial pressure (MAP). (B ) Heart rate (HR). The percent changes of MAP and HR relative to the baseline between the 4 groups were compared. All the values are presented as mean. T0, before propofol administration; T1, LOC; T2, 3 minutes after the administration of fentanyl and cisatracurium; T3, 1 minute after intubation; T4, 5 minutes after intubation; T5, 10 minutes after intubation.
