• The world's currently largest randomized controlled trial (RCT) on Covid-19 protection by face masks is just published.
• The study showed a reduction in risk for Covid19 by using a facial mask 
• There are, however, severe limitations in this study and much more to mask-wearing than provided by this study,
• In this episode, we go beyond the abstract for the details.

GET THE ABSTRACT SCREENING TOOL

It can be a challenge to screen papers for clinical relevance. As we go beyond the abstract in this podcast, we have created a screening tool you can use when reading an abstract from a clinical research paper.

Using that tool enables you to quickly screen an abstract from a medical journal for clinical relevance selecting only those you want to read. At the same time, you will know why you skipped the rest. Get it at https://www.precision-evidence.com/tool

NOTES:

• How to interpret the abstract
• What does it mean that wearing a mask "did not reduce the SARS-CoV-2 infection rate among wearers by more than 50%."
• Results from the study showed a small insignificant reduction in risk for Covid-19 by wearing a mask
• How many persons must wear a mans to avoid one person getting Covid-19
• The precision of the evidence with few exclusion criteria
• Evaluating the study population
• Study design and management
• Limitations
• Relate to CDC guidelines
• What can we conclude based on this paper?
