Table 3. Comparison of CI and SVI.

Time points	CI [L/(min·m2)]				SVI [mL/(beat·m2)]
	Group Pa (n=29)	Group Ra (n=28)	P-value		Group Pa (n=29)	Group Ra (n=28)	P-value
aEligible patients were randomized into either the "propofol group" (group P) or the "remimazolam group" (group R). In both groups, CI and SVI at each time point were normally distributed, expressed as mean ± standard deviation, and analyzed using Student's t-tests.bVariances of ΔMAPmax were not equal between the two groups (Levene's variance equality test, PCI at T3 = 0.008, PSVI at T3 = 0.008).Abbreviations: CI, cardiac index; SVI, stroke volume index; T0, after the patient entered the operation room and rested for at least 15 min; T1, BIS value decreased to 60 after the initiation of induction; T2, 4 min after administration of cis-atracurium; T3, 5 min after endotracheal intubation.
