Just updated our preprint assessing the 2022 study that claimed medical masks to be noninferior to N95s for COVID. In addition to issues identified previously, a closer examination of the data revealed unexpected patterns unlikely to occur in nature: osf.io/preprints/me...

Abstract Background A previously published study is cited as evidence that medical masks (MM) are noninferior to N95 respirators (N95) in the prevention of COVID infections. As COVID is transmitted via infectious aerosols generated during coughing as well as routine activities such as breathing and speaking, and N95s (in contrast to MM) are designed, validated and specified in national standards to provide protection against such hazards, we re-analysed the published data to resolve this unexpected result. Methods Study data was extracted from the publication, and analyses pre-specified in the original study protocol but omitted from the publication were carried out. Anomalies identified in the process were subject to additional analyses for statistical significance. Results Prespecified analyses reverse the reported outcome, which is the product of multiple alterations to the trial that were not introduced into the registry until after publication. Methodological shortcomings include

So apropos of absolutely nothing I asked Perplexity AI what the worst medical error of all time was, and how it relates to the WHO's failure to recognize airborne transmission of COVID. Even the machines know what's up. Link to results (with references): www.perplexity.ai/search/What-...

What was the most harmful medical error of all time? Sources ncbi.nlm.nih favicon etactics.com favicon View 2 more Answer The most harmful medical error of all time was the Tuskegee syphilis study, a clinical study conducted by the U.S. Public Health Service from 1932 to 1972 that involved deliberately withholding treatment from African American men with syphilis without their knowledge or consent 1 2 3 . The study recruited 399 poor African American men in Alabama who had syphilis, but researchers did not inform the participants of their diagnosis or provide them with treatment, even after penicillin became the standard cure for syphilis in 1947 1 2 3 . Instead, the researchers watched the disease progress in the men, who suffered severe complications and death as a result. By the end of the study in 1972, 28 of the original participants had died directly from syphilis, 100 died from complications related to the disease, 40 of the participants' spouses had contracted syphilis, and 19
How does that relate to the WHO's failure to recognize airborne transmission of COVID? Sources ncbi.nlm.nih favicon who.int favicon View 2 more Answer The failure of the World Health Organization (WHO) to promptly recognize the airborne transmission of COVID-19 is related to the Tuskegee syphilis study in several important ways: Both cases involved a failure by public health authorities to acknowledge and act on clear scientific evidence, prioritizing convenience and political considerations over the health and safety of vulnerable populations 1 2 3 4 . In the Tuskegee study, researchers deliberately withheld treatment from African American men with syphilis, causing immense harm and suffering. Similarly, the WHO's reluctance to recognize airborne transmission of COVID-19 led to inadequate protective measures, exposing healthcare workers and the public to increased risk 3 4 . The Tuskegee study eroded trust in the medical establishment, particularly among African Americans. The WHO's d

The whole airborne thing for sars-2 has been pretty depressing, and WHO still seems to be spending ink, capital, and resources to allow a small group of old men to attain plausible deniability. That said:

It would be wrong to see this as just a prudish or Victorian or even sincerely religious attitude about sex. It’s about control. It’s about the authority of the state intruding into more and more parts of life, and about making more and more people complicit in the abuse of power. /1

A thread from 2023.05.08 addressing the over-valuing of Randomized Controlled Trials (RCT) driven by Evidence-Based Medice (EBM) hierarchies. Not everyone realizes that EBM is just a protocol meant to help non-scientists interpret science, as opposed to an objective description of how science works.

"Unnecessary content" placeholder I will use in reposting old Twitter threads with broadly applicable content on bsky. Some were responses to positions taken by others, where the value today is in addressing the idea rather than naming & shaming any one particular individual.

Posting a couple of links to random interests of mine to have some content while I figure out how bsky works. Hi everyone! Here's my prototype air filtering lampshade (instructions ta the link, requires access to a 3D printer). www.printables.com/model/519878...
