	Group P (n = 125)	Group RP (n = 125)	RR (95%CI)	P
Hypotension	25(20%)	9(7.2%)	2.778(1.352–5.709)	0.003^a
TWA(mmHg)	0.31(0.15–0.67)	0.14(0.10–0.56)		0.003^b
AUT(mmHg min)	6.0(3.0–13.0)	3.0(2.0–11.0)
Duration of hypotension(min)	2.0(1.0–4.0)	2.0(1.0-5.5)

Notes: Values are medians with interquartile ranges (IQR), or n (%)
a P value was measured with the chi-square test.
b P value was measured with the 2-sample Wilcoxon rank-sum test.
Abbreviations: TWA, the time-weighted average; AUT, the area under the threshold.
