In Reply.—We thank Dr Browne for his pertinent comments on our article. We have not stated nor implied that one could estimate blood pressure from weight, but rather that there is a better correlation between blood pressure and weight than between blood pressure and height. There was no attempt on our part to predict any individual's blood pressure on the basis of his weight. If Dr Browne believes that we inferred this, we regret that we did not state explicitly that results of regression analysis should not be applied to individuals unless the correlation coefficient approaches unity. Lastly, we believe that Dr Browne has failed to understand our point that, in our study, black children appeared to have lower diastolic blood pressure than white children reported in other studies.
We cannot compare our study with any other, but we do suggest that this observation, under our stated conditions, warrants
