Inadvertently we did not reference three articles from 1978the two mentioned by Leumann and our own abstract.1 Both of Leumann's references confirmed that in children, as in adults with progressive renal failue, a straight-line relationship exists when plotting the reciprocal of the serum creatinine (SC) level or, occasionally, the logarithm vs time. They also examined the rate of change in SC for various disease categories in children, which was also previously investigated in adults.2,3
On the other hand, our recent paper4 considered whether we could have predicted early in the child's illness when he would reach his already known SC value just before dialysis was instituted.
