Table 6. Genetic correlation between iron parameters and left ventricular parameters.

Systemic iron status	Left ventricular parameters	rg	se	z	P	h2	h2 se	Intercept	Intercept se
The SNP-based heritability (h2) of the systemic iron status. LVEDV: left ventricular end-diastolic volume; LVEF: left ventricular ejection fraction; LVESV: left ventricular end-systolic volume; LVMVR: left ventricular mass-to-end-diastolic volume ratio; TIBC: total iron binding capacity; TSAT: transferrin saturation.
