I'm not attacking the study. But the more a study has to rely on survey information, rather than actual, or even better yet, controlled observation, the more likely it will have limited value.

I certainly would give the controlled double blind studies showing hydroxychloroquine ineffective more credence.



But you cannot really do that in this case. At the least you would have to force one group not to wear masks. It is not a study of a new drug, just about mask habits.

Masks are worthless unless you're wearing an N95 or a KN95 mask. Cloth and surgical masks are about as effective as using a screen door to block water.


Maybe if I post a description written for children from an epidemiologist from Bostonís Childrenís Hospital the above nonsense will stop being repeated.

Quote:
When infected individuals talk, cough, or sing, they generate large, wet droplets containing the virus that causes COVID-19. If youíre within 6 feet of someone who is infected, those droplets can land on your eyes, nose, or mouth and infect you, too. And if youíre very close physically to someone who is infected, you can potentially inhale some of the droplets as well.

The main benefit of wearing a mask is preventing spread of the virus. If you are infected yourself and wear a mask, the mask largely blocks those droplets from coming in contact with other people when you talk or cough.



Rxwine,

Perhaps I should quote what virologists and even Dr. Fauci said about it early on for you. Oh, and don't worry I'll rewrite some of it using smaller words and shorter sentences so that you can comprehend it, or perhaps have an adult read it to you. ;)

Why we are doing math analysis why don't we examine the false claim that Biden's tax plan will not raise taxes on those making less than 400k a year.



Warning issued for making a political statement. I don't mind a mathematical look at tax proposals, but just throwing out a political opinion is against forum rules.

The most reliable survey studies are usually designed so the intention is disguised. They tell you they are studying one thing, while they are actually recording some other reaction you're not made aware of. I say that, so when people see survey information, they don't automatically dismiss it without looking closer.

Going back to the positive table, if you add the group of case patients, adding the groups who often or always wore masks, there are 130 of them. Out of 153 who tested positive, that is 130/153 = 85% of them.

The same statistic, for those who didn't test positive, is (23+118)/159 = 141/159 = 89%.

Does anyone dispute that this is the 85% in question?



No, but using the W.H.O. estimate that 10% of the world population has been infected, the uninfected control group should have been nine times larger. Everything else remaining the same, a 9 to 1 ratio would show only 8.5% of the total number of subjects who always or often wore a mask fourteen days before the onset, became infected.

Nobody is talking about a blended average for how often positive cases wore masks.

It is supposed to be a discussion on statistics, which is allowed.
