CDC Buries Study Finding That Student Masking Has ‘No Statistically Significant Benefit’

Via ZeroHedge

Less than three months ago, the Centers for Disease Control published a mostly-ignored, large-scale study of Covid-19 transmission in US schools which concluded that while masking then-unvaccinated teachers and improving ventilation was associated with lower levels of virus transmission in schools – social distancing, classroom barriers, HEPA filters, and forcing students to wear masks did not result in a statistically significant benefit.

A few major news outlets covered its release by briefly reiterating the study’s summary: that masking then-unvaccinated teachers and improving ventilation with more fresh air were associated with a lower incidence of the virus in schools. Those are common-sense measures, and the fact that they seem to work is reassuring but not surprising. Other findings of equal importance in the study, however, were absent from the summary and not widely reported. These findings cast doubt on the impact of many of the most common mitigation measures in American schools. Distancing, hybrid models, classroom barriers, HEPA filters, and, most notably, requiring student masking were each found to not have a statistically significant benefit. In other words, these measures could not be said to be effective. -NYMag

According to the report, scientists believe that the CDC’s decision to intentionally omit the findings on student masking from a summary of the study amounts to “file drawering” the findings – the practice of burying studies that don’t have statistically significant results.

“That a masking requirement of students failed to show independent benefit is a finding of consequence and great interest,” according to Vinay Prasad, an associate professor in University of California, San Francisco’s Department of Epidemiology and Biostatistics. “It should have been included in the summary.”

Epidemiologist Tracy Hoeg, author of a different CDC study on Covid-19 transmission in schools said that “The summary gives the impression that only masking of staff was studied,” adding “when in reality there was this additional important detection about a student-masking requirement not having a statistical impact.”

As Twitchy notes, NYMag‘s David Zweig questioned why the US is requiring masks when other countries don’t.

David was joined by others pointing out similar facts:

But it’s not just this CDC study. There are no studies that Zwieg — or anyone — can find that “show conclusively that kids wearing masks in schools has any effect on their own morbidity or mortality or on hospitalization or death rate in the community around them”:

Meanwhile, as we’ve noted a few times in the past week, there are plenty of studies which conclude that masks provide minimal to no protection.

Masking is critical to the BASTARDS. It’s visual confirmation in creating the new reality that has swept through the mentally deficient, non-critical thinkers. And we can see there are a lot of them.
It satisfies the primal urge of tribal belonging. If everyone is doing it it must be the right thing to do. They don’t have to think and go through the machinations of what’s right or wrong. They are accepted and don’t stand out.

Can we please get those self-induced drowning numbers up?

Auntie remembers a looooong time ago; a scuba regulator issue at 40 ft. That was pretty hairy.

This idea is so fucking stupid that this gets a Darwin Award commercial contestant entry right out of the gate.

Don’t forget to release air from the lungs as one frantically makes one way to the surface. And no time to worry about the bends if just maybe one has dipped below the magical sixty foot mark during the dive.

That is a strange feeling when underwater and suddenly no air comes through the regulator.

They’re making these babies inhale their own carbon dioxide all day long for the benefit of these morbidly obese, unhealthy teachers who are afraid of becoming ill and could give a s–t less about the health of the children.

They play chess 7 steps out. They want the kids jabbed. And if kids were allowed to live relatively normal lives without masks, maybe, just maybe, some parents might question the need for the shot for their children.

They have done away with the need for scholastic test such as SAT for university entrance so it doesn’t matter if intelligent or not.
That is to discourage the idea of the home schooled crowd, providing a need for real education.

https://www.cnn.com/2021/05/27/us/baltimore-schools-failing-grades/index.html

From the article:
“For high school students, a failing grade will be replaced with “No Credit,” and for students in second through eighth grades, an “Unsatisfactory” or “Fail” will be replaced with “Not Completed.”
Students who receive these “incomplete” grades will still be able to continue on to the next grade level.
“In all of these instances, we want to emphasize the word ‘yet’. Not completed yet, no credit yet,” said Dabrowski.”

Little T’ra is not a nuclear scientist “yet”.
