191 patient RCT in Egypt comparing the addition of zinc to HCQ, not showing a significant difference.
Clinical recovery at 28 days was 79.2% in the zinc group and 77.9% control, p
Mechanical ventilation was used with 4 patients in the zinc group and 6 control. There were 5 deaths in each group.
No information on baseline zinc values was recorded. We note that Egypt has a low rate of zinc deficiency so supplementation is less likely to be helpful in Egypt [1, 2]
