This study deals with a controversy about the correlation of KT/V
and nPCR in CAPD. The authors measure nPCR in the conventional
manner but clearance is calculated by the iohexol method which is
entirely independent of urea measurements and so avoids the problem of
mathematical coupling. They find that the correlation between clearance
and nPCR is not as strong when iohexol is used but still exists with an r
value of 0.46, which is significant.
This study supports a growing impression that the correlation
between small solute clearance and protein intake in CAPD is real and
significant, although it may not be as strong as was originally thought.
