Podcast 617: Masks and Understanding Data

Podcast 617: Masks and Understanding Data

Contributor: Peter Bakes, MD

Educational Pearls:

  • Recent study looked at if mask wearing protects the mask wearer from infection
  • This group found 1.8% of mask wearers got COVID while 2.1% of non-mask wearers became infected, which was not statistically significant
  • This was not statistically significant and has been used to justify not wearing masks by some groups
  • While the numbers look small, it's close to a 20% reduction in infections for the mask wearers
  • The results reported had concerns for being underpowered, meaning the studies population may not be big enough to draw definitive conclusions
  • Many limitations of study including how wearing a mask may protect others
  • Unfortunately, studies like these can lead to misinterpretation and distortion
