Just looked @ CDC's AZ school-mask study. What a load of garbage. Here’s why:
-No info on actual # of cases, or # of kids in school
-No info on testing levels
-52% of schools WITH mask reqs were small (<850) vs. 13% in No-Mask Schools
-Case rates 2.4x in no-Mask Areas

When numbers are missing, it tells you something. The key number here SHOULD be, number of cases/child. That they chose outbreaks instead is...fishy. That 52% of masked schools were small, vs. 13% of un-masked, is important. Fewer kids in schools = Outbreak less likely.

It's kind of amazing they needed to do this. The CDC basically set its "close contact" rules for schools to "prove" masks work.
In situations where both kids are masked, a masked contact DOESN'T count as a contact, AND THUS DOESN'T NEED TO BE TESTED.

The same sleight of hand is also being used to depress vaxed case numbers, as vaxed "close contacts" don't need to be tested.

To re-cap we are missing the most important information here: total cases/total students. We also have a system rigged to favor masking as masked close contacts kids DON'T need to test. AND un-masked schools R much larger. This study stinks to high heaven of data manipulation.

Once I saw the CDC guidance on exempting masked close contacts, I KNEW they would be using this to manipulate the data. What surprised me is that even with this leg-up, they still had to resort to even further manipulation. (link to study here)
