That study examined no such thing. The second sentence states:
Wearing a face mask can reduce transmission of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19) (2), and many colleges and universities mandate mask use in public locations and outdoors when within six feet of others.
First, the citation for (2) referenced here claiming that masks reduce transmission is a dead link, so I have no idea what they're basing this assertion upon. Second, if you've paid any attention to the news, the six feet rule was complete nonsense that, according to Fauci, "
sort of just appeared" and "an empiric decision that
wasn't based on data".
So already, just two sentences into this "study",the authors tout the six foot rule, which just appeared out of thin air and wasn't based on any data, yet they
begin with the assumption that masking and six feet of distance reduces SARS-CoV-2 transmission. Not a great start.
So if they're not studying mask efficacy, what are they studying? As CDC is wont to do with these "studies", there is an infographic, and that infographic gives us insight into what they were observing.

The takeaway here isn't that masks reduce the transmission of SARS-CoV-2. In this study, they pretend that's just a given. No, what they were studying was what percentage of people were wearing masks, and what percentage of people were wearing them correctly. There wasn't even an endpoint where they looked at number of infections. This was literally just watching people walk by to see if they wore their mask correctly over their mouth and nose.
When you posted an MMWR article, I thought surely you'd fall back on one of the more infamous ones. Perhaps the
hairdresser "study", or the phone survey where the CDC laughably concluded that mask use could reduce the risk of a positive COVID test by up to a whopping 83%! Heck, even if you just made a mask out of your olds Guns 'N Roses T-shirt, they said you could reduce your risk by 56%. This is prima facie nonsense.

Here, just look at the scientific rigor that was undertaken to arrive at this conclusion.
After obtaining informed consent from participants, interviewers administered a telephone questionnaire in English or Spanish. All participants were asked to indicate whether they had been in indoor public settings (e.g., retail stores, restaurants or bars, recreational facilities, public transit, salons, movie theaters, worship services, schools, or museums) in the 14 days preceding testing and whether they wore a face mask or respirator all, most, some, or none of the time in those settings. Interviewers recorded participants’ responses regarding COVID-19 vaccination status, sociodemographic characteristics, and history of exposure to anyone known or suspected to have been infected with SARS-CoV-2 in the 14 days before participants were tested. Participants enrolled during September 9–December 1, 2021, (534) were also asked to indicate the type of face covering typically worn (N95/KN95 respirator, surgical mask, or cloth mask) in indoor public settings.
This report describes face mask or respirator effectiveness in helping protect against COVID-19 infection.

So the CDC called 534 people up who had self-reported testing positive for COVID and asked them if they'd been in public and if they'd worn a mask. And from this rock solid selection of participants, they arrived at this conclusion. All this study really confirmed is that people who were true believers in masks were more likely to report that their mask was beneficial. And the CDC has to know that. Do you see the fine print on that infographic? The part that says "Not statistically significant"? What are we doing here? This isn't science. This is pure propaganda. Starting with a desired conclusion and then cherry-picking data to support your predetermined conclusion.
But you know how I really know that mask guidance was truly nonsense? Just a week before Christmas, I had to take my daughter to the ER. This was at the height of respiratory illness season. In fact, I'd just read an article that said cases were up, up, UP! Yet when we got to that ER that had well over a hundred sick kids, not one receptionist, resident, nurse or, doctor was wearing a mask. Not one. I saw exactly one family in the waiting room that was masked. Think about how remarkable that is. This was a very large hospital. And yet NOT ONE of the medical professionals that were caring for these kids had a mask on AT THE HEIGHT OF FLU SEASON.
It was well-known and accepted before COVID that mask use did not reduce the risk of respiratory disease transmission. That's still true. Maska are little more than "
comfort blankets" that do little to reduce the spread of respiratory illness.
'We are entrenching bad behaviour'
However, other studies have cast doubt on their effectiveness. A subsequent Danish study involving 6,000 people concluded that there was no statistical difference in infection spread in non-wearers, while data on US states with non-mandated usage failed to show a correlated uptick in cases.
"The public were demanding something must be done, they got masks, it is just a comfort blanket," Dr Axon noted. "But now it is entrenched, and we are entrenching bad behaviour.
"All around the world you can look at mask mandates and superimpose on infection rates, you cannot see that mask mandates made any effect whatsoever.
"The best thing you can say about any mask is that any positive effect they do have is too small to be measured."
Dr Colin Axon warned some cloth masks have gaps that are invisible to the naked eye, but are 5000 times the size of viral Covid particles
