Abstract

In Reply.—  Dr Engelberg is correct in stating that the sample was not random. As a matter of fact, in the United States at this time, there is no way to obtain a random selection of boxers, since boxers are not registered in a central registry and we must depend on obtaining data either from all boxers found or a selection thereof. In our case, we saw every boxer who agreed to be studied. We do not agree that "with such a sample, attempting any sort of statistical analysis is incorrect." The statistical analysis and conclusions pertain to our study only. The conclusions may or may not be applicable to boxers in general. We would like to point out, however, that our boxers had relatively few bouts, and we feel justified in assuming from the data that in those boxers having more bouts, worse CT scores would have been found.
