Association between creatinine-based estimated glomerular filtration rate (eGFR), cystatin C and number of cardiac calcifications^a

	Odds ratio (95% CI)	P-valueb
eGFR
>60 mL/min/1.73 m2	Reference
45–60 mL/min/1.73 m2	0.98 (0.91–1.05)	0.566
<45 mL/min/1.73 m2	1.15 (1.03–1.29)	0.015
Cystatin C (mg/L)	1.12 (1.03–1.23)	0.013

Data presented as OR (95% confidence intervals).

^aThe total number of cardiac calcifications, summing the presence or absence of mitral annular calcifications (MAC), aortic annular calcifications (AAC) and aortic valve sclerosis (AVS). Each defined as the sum of mild, moderate or severe versus none, with the reference group being individuals with no calcifications in any of these structures.

^bAdjusted for age, gender and race.
