The Centor criteria are not for children
The Centor criteria were derived form an adult population. They
withstood the test of time and have been validated in adults in a number
of studies; however, they were not intended to predict streptococcal
pharyngitis in children. Two of the Centor criteria, fever (temperature
>38 C) and exudate were not found to be significantly associated with
streptococcal pharyngitis in children 1-3. The use of the Centor criteria
as inclusion criterion in this study could have introduced selection bias.
Why did not the authors use a pediatric prediction model?
Another question for the authors, on what physiologic bases can they
explain these findings in comparison to their findings in adults? Why
adults would recover from streptococcal pharyngitis faster if they take
penicillin but not children? Could that simply be because adults complain
