OI, osteogenesis imperfecta; BSA, body surface area; PAO, proximal ascending aorta; MPA, main pulmonary artery; LAD, left atrial anteroposterior dimension; LVEDd, left ventricular end-diastolic dimension; RVEDd, right ventricular end-diastolic dimension; IVST, interventricular septal wall thickness; LVPWT, left ventricular posterior wall thickness; LVM, left ventricular mass; LVEF, left ventricular ejection fraction.

β, Regression coefficient. Adjusted for age, gender, and BSA.
