Last week, the Guardian, The Times, the Metro, New Scientist and Forbes claimed a study shows mask-wearing cuts the risk of Covid by 53%. This isn’t what the study says. It actually says mask-wearing is “associated with” a 53% risk reduction, but that due to the limitations of the research, “it was difficult for our review to draw a… causal conclusion”.
We published our fact check the next day, and we’re pleased that the Guardian, The Times and the Metro have updated their articles off the back of this. We’re disappointed the New Scientist and Forbes have not yet followed suit.
