Looking at the study it doesn’t look like the participants in the trial were randomised—rather if you wanted to use Taffix you could.
If I’m right I’m not sure what to make of it—you could have selection bias either way. More conscientious/concerned people took it or people with jobs where they had higher exposure levels took it. I would guess the former effect would be larger but not sure.
