  1. Change in Kt/V was calculated at Kt/V at 2 years – baseline Kt/V; positive changes were classified as improvements and negative changes as worsening. Values are medians (interquartile range). BSA, body surface area; IVSd, interventricular septum thickness (diastolic); LVPWd, left ventricular posterior wall thickness (diastolic); LVIDd, LV internal diameter (diastolic); LVIDs, LV internal diameter (systolic); LVMI, LV mass index; LA, left atrium; RV, right ventricle; LVEDV, LV end-diastolic volume; LVESV, LV end-systolic volume; LVEF, LV ejection fraction; SDI, systolic dyssynchrony index; NT-proBNP, N-terminal pro-B-type natriuretic peptide; WCC, weekly creatinine clearance.
