Values shown are means ± standard deviation or percentages, adjusted for age, race, education, and network. EF: ejection fraction; LA: left atrial; LA/Height: Left atrial systolic dimension indexed to height; E: Mitral valve early diastolic filling velocity A: Mitral valve late diastolic filling velocity; IVRT: Isovolumic relaxation time; BSA: Body surface area

Models were fit with log-transformed values. The means have been back-transformed to raw units for interpretability.
