Dear colleagues,
A year ago we investigated the Cockcroft formula for creatinine
clearance by comparing all our measured clearances of the
previous 2,5 year (n=416) with a calculated Cockcroft result. Our
results are attached to this e-mail as an Excel-sheet of 152064
bytes (I have virus checked it, but one can never be to careful in
this). I think these results prove that the Cockcroft formula can over-
or underestimate the true clearance by a factor of more than two.
Therefore one should be very careful when using a Cockcroft
clearance.
Best regards,
Christian
