Researchers publish "debunking" of a
hydroxychloroquine study touted by Trump

Researchers on Wednesday published scathing critiques of a study
President Trump repeatedly touted on Twitter.
That study, published earlier this month in the International Journal
of Infectious Diseases, claimed to show that hydroxychloroquine
saved lives. President Trump tweeted about it enthusiastically.
"The highly respected Henry Ford Health System just reported,
based on a large sampling, that HYDROXYCHLOROQUINE cut
the death rate in certain sick patients very significantly.
The Dems disparaged it for political reasons (me!).
Disgraceful. Act now," the President tweeted on July 6.
But the study had multiple errors, flaws and biases, 
according to letters to the journal's editors.
Henry Ford doctors chose to prescribe hydroxychloroquine to
some patients, but not to others -- and that may have
introduced some bias into the study, the letters suggested.
For example, the patients in the Henry Ford study who were
given hydroxychloroquine had fewer risk factors for heart disease,
the Albany researchers, Eli Rosenberg, David Holtgrave and
Tomoko Udo, wrote in their letter.
Also, the hydroxychloroquine patients were more than twice as
likely to be given steroids, a treatment known to be effective
against Covid-19.
The Detroit study was not a randomized clinical trial, 
which is the gold standard in medicine and helps avoid these
potential biases. In such trials, patients are randomly assigned
to take a drug or not take it, which means the two groups should
be very similar.
"As a result of the flaws in the analysis the conclusions
reached in [the study] are invalid," Graham Atkinson, an independent
consultant in health care policy, wrote in one of the letters.

NOTE: just now on LIVE TV, Dr. Fauci was asked about the above study
and just destroyed it.... Completely dismissed it. He states that to date
there have been NO valid, randomized-placebo-controlled studies that have
demonstrated efficacy but he would be the first to announce it if it happens.
He further stated that there have been valid, randomized-placebo-controlled
studies done and none of them proved effective for covid-19
