Values shown are means ± standard deviation or percentages adjusted for age, race, education, and network.
LV: Left ventricular; PWTd: diastolic posterior wall thickness; IVSd: diastolic intraventricular septal thickness; LVIDd: End-diastolic LV internal dimension; LVMI: LV mass index (indexed to body surface area); RWT: Relative wall thickness (PWTd+IVSd)/LVIDd
*
Models were fit with log-transformed values. The means have been back-transformed to raw units for interpretability.
**
Unadjusted percentages are shown. Analyses were not done to compare LV geometry across the groups adjusting for covariates due to the limited number of subjects with concentric geometry types.
