Correction to: Altered oscillation of Doppler-derived renal and renal interlobar venous flow velocities in hypertensive and diabetic patients

In the original publication of this paper the legend of Fig. 1 should read as: Fig. 1 Pulsed Doppler flow velocity recordings of the aorta (a), right renal artery (b), right renal interlobar artery (c), inferior vena cava (d), right renal vein (e), and right renal interlobar vein (f). PSV peak systolic velocity, EDV end-diastolic velocity, V _MAX maximum velocity, V _MIN minimum velocity
