FYI, update from a hospital in France that they stopped the hydroxychloroquine and azithromycin combo due to adverse cardiac effects.
Don’t know enough about the specifics there but if this combo is not good for the 1% with high-risk of cardiac effects, then it is not effective on the population that might be the highest risk of dying from this. Just another point to keep in mind when evaluating outcomes with this treatment and how this is a bias in the people selected for the treatment.
