All the study did was *fail to demonstrate a statistically significant benefit* of a specific, half-measures combination of filter units - which is unsurprising when you actually read it!
Of 1778 residents in "intervention" care homes, only 208 (~1 in 8) got an in-room HEPA (on the lowest setting).

Diving into the article, the title itself is directly mis- (arguably dis-)information, and the manipulative image caption is inappropriate ("monkey business" indeed).
The study did (could) NOT show "Air filters don’t stop you catching infectious respiratory diseases" - a misleading exaggeration.

This is the same error as the "widespread failure" driving assumptions and policies that "were and are wrong" that the UK COVID Inquiry just highlighted.
If that screwup magically didn't kill anyone, it lets him off the hook for his involvement. Huge commitment bias right from the start.

Module 3 of the UK COVID Inquiry is out. Encouraging to see explicit recognition of the "widespread failure" of clinical leaders to understand aerosol science, and the "clear failure" of IPC leaders to understand that they might be wrong. #medsky #scisky

The usual scientifically illiterate gibberish from deeply conflicted aerosol transmission deniers.
🧵(1/n) An unfortunate example of confusion around the value of RCTs common to practitioners with limited research training. RCTs are a useful scientific method, but they are only a small part of the biomedical researcher's deep toolbox.

"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.

You should be embarrassed for promoting such a laughably amateur and ignorant study.
Here's what an actual expert has to say:

They never measured the air. The filters were run at settings chosen for noise and comfort in communal rooms (low flow). They didn't even calculate room volumes — and no tracer, particle, or bioaerosol data confirms the intervention lowered airborne pathogen concentrations anywhere. 1/
Curious to hear what you think of this Kim @kprather.bsky.social ?

The lead author has an *immense* undisclosed COI to deny aerosol mitigations are effective, due to his role in the "very big mistake" that wasted "an enormous number of lives".

Even now there have been no consequences - or even investigations.

There's a deeper story here that's desperately in need of coverage. Contrast Dr. Filiatrault's informed understanding of how to prevent respiratory infections with the disastrous decisions made in long term care facilities in Montreal in 2020.

I want to highlight a story from May 2020 that really hammers home the mismanagement of the pandemic by public health and infection control leaders.
Nursing home in Montreal, COVID everywhere, staff sick, people dying. It killed a significant proportion of the people there.

Ironically, the Toronto public health leaders who blew the calls on SARS are the ones it made famous - treated as heroes for cleaning up their own mess without killing too many people. You don't hear about the people who got it right, and prevented SARS in BC.
