The three should be considered as one. Not good science at all. Even off the shelve, cold medicines have a variety of medications that work in conjunction together.
Hydroxychloroquine regulates the activity of the immune system, which may be overactive, thus allowing the Z-Pak and vitamins to work more effectively.
It’s like testing aspirin to see if it will stop a runny nose. If they wanted to test Hydroxychloroquine effectiveness they should test the Z-Pak / Vitamin combo with and without it. But still have all three in connection as part of the test.
Sorry, but all wrong. All you are doing is showing your ignorance of proper scientific research. It’s your opinion and you’re entitled to it, but science doesn’t accept opinions.
An appropriate study would have a HCQ only group, an HCQ+Zpak group, a Zpak+Zinc group, a HCQ+Zinc group, and a placebo group at a minimum. That involves a LOT of people and a LOT of time and money.
Note...I think that doctors “should” have the option to prescribe what they feel best, but the needed information for absolute assurance of scientific validity just does not currently exist.
