But is it not inconceivable that you can simply add sample without ever using it. That is fraudulent, as you may know and I doubt that Dvorak can get away with it. My belief is that they did use Senegal, otherwise why would they mention Senegal? What is possible, is that they may have parsed the data in order to produce multiple reports, which is not unusual in research studies. I doubt that you will find a report from then based only on a Senegalese sample but if you do please share. What I think they have done is to use the samples integratively in several of their reports.
Enugu II,
I have read and re-read the links you shared, and I have still found no proof that Senegal was ever part of the original Dvorak sample data, and in fact, I can prove definitively that Senegal was never part of the original data:
Here is a detailed report of the Dvorak MRI Age determination by MRI study published online in 2006:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2465138/Please pay attention to Table 2 where it shows the exact break down of adolescents by country:
https://www.ncbi.nlm.nih.gov/pmc/articl ... objectonlyNo Senegal. They were not part of the original 496 adolescents clearly.
Now, I am not saying the Dvorak grading system has not been recalibrated since the original test with Senegalese data. I am just saying that I have yet to see any definitive report explaining exactly when and how Senegalese adolescents participated in such an exercise, at least to the level of detail that we have seen in the links I have shared above.
Yet, at some point (at least from 2009 onwards), Dvorak and FIFA started adding Senegal as one of the countries in their original sample size (which we now know for certain was not the case). So it begs the perfectly valid to question of when Senegalese adolecents were tested and used to calibrate the Dvorak MRI scaling system.
I will keep looking for any study showing in detail the Senegalese MRI test and share what I have as soon as I find anything.
