Resistance to Erythropoiesis-Stimulating Agents Is Associated with Arterial Microcalcification in Early Hemodialysis Patients

Table 4

Arterial microcalcification according to EHRI values categorized into tertiles.

Arterial; microcalcification	EHRI tertiles (mean ± SD)			𝑃 value
	T1 (𝑁=28); (3.3±1.7)	T2 (𝑁=27); (10.2±3.3)	T3 (𝑁=27); (29.8±11.8)
AMiC negative	22 (78.6)	16 (59.3)	11 (40.7)	0.017
AMiC positive	6 (21.4)	11 (40.7)	16 (59.3)
	IU/kg/week recombinant human erythropoietin
	≤300 (𝑁=71)	>300 (𝑁=11)
AMiC negative	45 (63.3)	4 (36.4)		0.086
AMiC positive	26 (36.6)	7 (63.6)

AMiC: arterial microcalcification; EHRI: ESA hyporesponsiveness index.
