Well written, interesting article.
Ok, I agree that in this world there are flawed or rigged studies. I agree there are unethical study designers. This can be generalized to any field, endeavor, persuit. I would have agreed before reading the article. Is it your premise that the study I reference was deliberately rigged? Or unintentionally biased to create the results they hoped for?
Reading the parameters and findings and such described in the abstract, it looks legit to me. It included 500 test subjects. I believe this is noteworthy re validity and statistical anomalies and so on. They added a single variable, a SPECT scan, to test its efficacy in the diagnostic procedure.

If he is not the ethical, competent, caring, reliable Doctor I assert he is, then what is his end game?
I don't see infomercials pushing these services. The patients find the Amen Clinic, the Clinic doesn't go out and solicit them.
