N=1.
Me and my 2 year old had covid. My wife started ivermectin and never got sick. Shared bed and sick 2 year old wants mommy.
Ivermectin didn't work for me (diarrhea) but my fever went from 102.7 down to 99 12 hours after HQC after 6 days of a slow downward spiral (fever kept going up and up every day). So for me, my take is the drugs absolutely worked.
