Age (per 10-year increase)	0.23 (−0.34 to 0.80)	0.416	−0.25 (−0.74 to 0.24)	0.305
Male sex	0.87 (0.04 to 1.70)	0.041	0.06 (−0.77 to 0.88)	0.891
High lipoprotein(a) group	0.04 (−0.59 to 0.66)	0.902	0.17 (−0.44 to 0.78)	0.573
Systolic blood pressure (per 10 mm Hg increase)	0.05 (−0.18 to 0.29)	0.639	0.10 (−0.12 to 0.32)	0.387
Corrected LDL-C (per mmol/L increase)	0.19 (−0.11 to 0.50)	0.216	−0.07 (−0.36 to 0.23)	0.648

Data are standardised coefficients (β) with 95% CI.

Adjusted R²=0.40 for the univariable analysis with aortic valve calcium score and adjusted R²=0.35 for the multivariable analysis.

AU, Agatston units; LDL-C, low-density-lipoprotein cholesterol; NaF, sodium fluoride.
