Look over the original study. The mode of action of hydroxychloroquine in fighting the virus is that makes it easier for zinc to enter the cells. However without supplements it renders the patient zinc deficient. This is pharmacology 101. If they used a group of severely ill patients as their group and never gave them zinc sulphate or similar, they may as well give them molecular-grade water while they're at it. You need to add the zinc.
