I'm sure they did, and cherrypicked 1910-1030 to do soauthors pooled 72 studies
\do you think surgeons should stop using masks when they operate ?
It blows my mind that this is even a thing.
A post or two ago I mentioned a meta-analysis about masks and forgot to include a hyperlink to the study. I know many of you are looking for it, so here it is. In short, the authors pooled 72 studies to assess how different public health mitigation measures (like masks, socially distancing, handwashing, etc.) impacted COVID19 infection. They found that some public health measures don’t really work. But, mask wearing reduced COVID19 infection by 53%. (For the record, this isn’t the only publication that shows masks work. For example, here are three studies that show they work well in schools.)Mask effectiveness is certainly dependent on the type of mask, though. This is why a layered approach (vaccine, mask, ventilation, testing) is crucial, especially in light of Omicron. The Wall Street Journal published a great graphic earlier this week comparing the protection of different types of masks:

Actually, your chart is a good reason not to require masks.
Even the N95 masks will allow transmission- just at a much slower rate.
Mask requirements- according to the data provided- will just extend the pandemic rather than allow it to burn out quicker.
What about your eyes?It blows my mind that this is even a thing.

This is why you wear masks. It prevents the infected from spreading the virus.
You don't wear a mask to protect yourself.
A 350,000 person study in Bangladesh reported 11%.Sounds about right.
Of course, in TrumpWorld, if it's not 100% effective always, it's never effective, at all, ever. And it's fake news. And a conspiracy. And Hitler.
"Some" is good.A 350,000 person study in Bangladesh reported 11%.
When it comes to mask and vaccine percentages, it's a case of picking one study from the many to supports one's agenda, then run with it. From the very start, masks offer 'some' benefit and trying to quantify the 'some' part is to pick the study that you want.
There are thousands of examples of fully masked and unmasked contracting flu, coronaviruses. I haven't worn one but I don't care if someone does or doesn't. It's their choice.

The flu was virtually eradicated last year because ppl wore masks. The flu is barely a blip on the radar in countries where mask wearing during flu season is customary. We on the other hand who don't wear masks in america during flu season and suffer hundreds of thousands of hospitalizations and tens of thousands of deaths. So tell me again how masks don't work against flu or covid.

Wrong.
If the flu had been eradicated last year, there would be no flu to expand this year.
Obviously what happened instead is the testing was bad, and they were falsely labeling flu as covid.

CDC Finally Admits PCR Tests Unable To Differentiate Between Flu And COVID, Withdraws Its Use
The Centers for Disease Control and Prevention (CDC) recently published an announcement on its website saying that the agency will no longer honor the emergency use authorization of the PCR test for COVID testing beginning January 1, 2022. They are now encouraging the use of another COVID test.
According to the CDC, it will withdraw its request to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) of the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel, the assay which was first introduced in February 2020 to detect COVID. To prepare for this change, the agency has ordered clinical laboratories and testing sites that have used the PCR assay to select and begin their transition to another FDA-approved COVID test.

You're trying to say that the mask stopped the flu but not covid. That's laughable. Yes, tens of millions were wearing or not wearing and still became infected. Basically, a wash. Your body didn't come attached with a mask because the immune system in healthy people is completely capable of destroying a virus, bacteria, protozoa, etc. However, if you're obese, eat a lot of junk food, have underlying conditions, high blood pressure, etc, your immune system is compromised so I understand why someone would want to wear one. It may/may not work but there's a chance.
