High prevalence of long QT intervals in dialysis-dependent CKD patients with the highest FGF23 levels. A Distribution of plasma FGF23 levels in baseline samples of 33 patients with dialysis-dependent CKD. B Prevalence of long QT intervals > 450 ms along the FGF23 ascending quartiles. C ECG waveforms showing QT interval duration in a representative patient from FGF23 Q1 (black) and from Q4 (red). D With increasing quartiles of FGF23, the prevalence of very long (> 490 ms) corrected QT (QTc) intervals significantly increased (P < 0.001)
