Task: Answer Verification
Input (English): Question: Is extrapolation of reciprocal creatinine plot reliable in predicting the onset of dialysis in patients with progressive renal insufficiency?
Answer: The onset of dialysis cannot be predicted by extrapolation of the reciprocal creatinine plot because of individual variation in the renal function that require dialysis. Dialysis would be almost imminent in some patients by the time serum creatinine reaches a level that allows accurate construction and extrapolation of a plot.
Output (English): no
