The correlation and agreement between MAP from radial and femoral arteries in all of the population and each subgroup.

	Correlation (r)	Bias (95% CI)	95% LOA (mmHg)
All (n = 706)	0.89	− 7.6 (− 8.2 to − 7)	− 24.1 to 8.5
MAP ≥ 65 mmHg (n = 458)	0.88	− 4.2 (− 4.8 to − 3.6)	− 17.1 to 8.7
MAP < 65 mmHg (n = 248)	0.63	− 13 (− 13.9 to − 12)	− 28.8 to 2.9
NE < 1 µg/kg/min (n = 485)	0.89	− 6.7 (− 7.4 to − 6)	− 22.3 to 8.9
NE ≥ 1 µg/kg/min (n = 221)	0.87	− 9.6 (− 10.8 to − 8.4)	− 27.3 to 8.1
NE < 0.5 µg/kg/min (n = 170)	0.88	-7.9 (− 9.2 to − 6.6)	− 25.3 to 9.5
NE ≥ 0.5 µg/kg/min (n = 536)	0.89	− 7.5 (− 8.2 to − 6.8)	− 23.7 to 8.6

CI: confident interval, LOA: limit of agreement, MAP: mean arterial pressure, NE: norepinephrine.
