[quote hamstersarse]this is nonsense and either you know it and you're here maliciously peddling misinformation, or you don't know it and you need to be told that you are talking absolute rubbish. There's a huge amount of evidence.
The irony

have you actually read the evidence summary? Because this isn't the big 'AHA' moment you think it is. Those figures are from preliminary DfE analysis based on schools reporting. Which come with a lot of caveats and is not peer reviewed.
This is also in the summation:
Face coverings can be effective in contributing to reducing transmission of COVID-19 in public and community settings. This is informed by a range of research, including randomised control trials, contact tracing studies, and observational studies – assessed
most recently by UKHSA, described in a review conducted in November 2021.7 The review’s conclusions were broadly in line with those of a previous Public Health England review; however, the addition of randomised control trials and substantially more
individual-level observational studies increases the strength of the conclusions and strengthens the evidence for the effectiveness of face coverings in reducing the spread of COVID-19 in the community, through source control, wearer protection, and universal masking.
So would you like to explain what the irony is here?
