5/22/2020: Malaria drug; yes or no? The results are based upon patient selection, the common denominator of medical treatment.
That is why reports and opinion are widely diverse on the use of hydroxychloroquine; yes or no. The latest today in very respected journal: Lancet.

The conclusion was no benefit and in fact worse results than not using it.
The subjects (research word for patients) were all sick enough to have been placed in the hospital. They were not patients who showed early symptoms of coronavirus infection. Those so sick they are hospitalized: NO!
Those treated early in the disease get a YES when this is the patient selection criteria.
Allow me to give you an analogy. Aspirin has been reported as beneficial as a preventative for heart disease. Aspirin is not the primary treatment for a patient hospitalized in heart failure.
