Association of Radial Artery Access with Reduced Incidence of Acute Kidney Injury

Table 2

AKI by the access site and Mehran risk group.

N	Mehran score (predicted risk of AKI)	Arterial access site	AKI rate (%)
8,053	≤5	Radial	2.7	0.02
	7.5%	Femoral	3.7
3,994	6–10	Radial	7.3	0.03
	14.0%	Femoral	9.2
1,676	11–15	Radial	14.1	<0.01
	26.1%	Femoral	20.3
354	≥16	Radial	29.4	0.10
	57.3%	Femoral	38.3

The percentages shown are the risk of developing AKI calculated from the Mehran risk score as reported in the original manuscript [20]. Abbreviations: AKI = acute kidney injury.
