The first large, randomized controlled trial of its kind showed no statistically significant difference in COVID-19 cases between people who wore masks and those who did not.
The Danish study published this week in the Annals of Internal Medicine found that a “recommendation to wear a surgical mask when outside the home among others did not reduce, at conventional levels of statistical significance, incident [COVID-19] infection compared with no mask recommendation.”
Among 6,000 participants in Denmark, half were told to wear masks and half were not. The researchers found 42 of the participants who were told to wear masks contracted COVID-19, while 53 in the control group got the disease.
The authors concluded the difference was not statistically significant.
