efficacy of masks against COVID comes from observational studies. Due to the paucity of evidence from RCTs, some systematic reviews have included the observational studies along with the RCTs. As of August 2023, RCTs played a relatively small role in the evaluation of non-pharmaceutical interventions during the pandemic

I think it's worded fine as it is. I'm good with the changes that were not reverted, and the status quo for the rest. If you want to propose more changes, up to you. I'm not clear on which review "made clear it wasn't rigorous"; it seems pretty unlikely that a review would negate itself like that. If

Overall effectiveness of these interventions was affected by clinical heterogeneity and methodological limitations, such as confounding and measurement bias. It was not possible to evaluate the impact of type of face maks (eg, surgical, fabric, N95 respirators) and compliance and frequency of wearing

However, within hospitals, severe restrictions due to SARS resulted in delays in treatments for cancer and surgeries, and the continuous, universal use of N95 respirators and other forms of personal protection was stressful for health care workers. Our experience suggests that the spread of SARS-CoV

much discussion on a single source, doesn't that indicate it might be a little problematic to include? IMO, better to focus on one source, and mine it to make sure it stands up to scrutiny. Picking poison apples being less likely if you only pick one, even if potentially more of the apple could be

A 2023 systematic review from the Cochrane Collaboration said the evidence from randomized controlled trials was still inconclusive over whether masking prevented the spread of influenza/COVID‐like illness through a population, noting that the answer could be different for different viruses. This

differing views, which is not what we are supposed to do. I'm not sure what specific changes you have in mind this time, but to be clear, consensus so far is clearly against removing the Cochrane source or mention of RCTs, so it should not be attempted again. We can see if anyone else weighs in.
1731:
There are two types of evidence for the efficacy of masks: observational studies, and randomised controlled trials (RCTs). While RCTs are more robust, they are too impractical for many public health interventions, yielding insufficient statistical power and validity. Most of the evidence for the

template is not necessary and I will likely remove it soon. This isn't really a mathematics topic except in the sense that every science topic involves math to some extent. As Bon courage stated, preprints are useless (this one is over a year old but apparently never published). If the 2024 ASM

HCWs were excluded if they (1) were unable or refused to consent; (2) had beards, long moustaches, or long facial hair stubble; (3) had a current respiratory illness, rhinitis, and/or allergy; or (4) worked part-time or did not work in the aforementioned wards or

Cochrane review was criticized for combining studies about influenza and about COVID, which could "yield invalid conclusions". Another 2023 systematic review, by the Royal Society, found the evidence from RCTs was that masks reduced risk by 12% to 18%.

As for the other reviews, "judgement on methodology not changing the article"... is cutting it a little close IMO, given that prose is a concern and mining a source is a policy. We have to make judgements all the time-- that's the difficulty of

by means of respiratory droplets can be controlled in many settings with less restrictive measures (e.g., the use of surgical masks in quarantine). Studies examining the costs and effectiveness of various control measures are under way.

Actually, I caught a mistake in the lead citation, made by me, that was not said during the discussion. Specificity next time would have reduced the temperature, and got me to realize my mistakes in a shorter period of time. With that

Participants were randomized by ward to three arms: (1) medical masks at all times on shift; (2) N95 respirators at all times on shift; and (3) targeted (intermittent) use of N95 respirators only while doing high-risk procedures or

As for that discussion you linked, I think one has to loop back around to the top to see a noted omission in the discussions: compliance. As I said, you can have discussions all day without realizing the work already done (NIOSH TB

Of course I bloody read it; what kind of question is that? BMJ is also reputable, but that doesn't mean you get to remove a Cochrane review with a misleading edit summary. There was already much discussion about how to include this

Various case-control and population-based studies have also shown that increased levels of masking in a community reduces the spread of SARS-CoV-2, though there is a paucity of evidence from randomized controlled trials

Unless the RCT study emphasizes worker training (required under 29 CFR 1910.134), it should probably be removed. Currently, I'm in the process of removing these RCT studies, but getting it right might take a

Masks are not of equal efficacy. While N95 masks outperform surgical masks in filtration, healthcare worker population studies have not shown a significant difference between the two, as of June 2021.

So, I'm not receiving much substantive feedback concerning this diff. I mean, it could be worded better, maybe certain phrases could be refined, additional citations and words could be added (see

On a second read, yeah sure, I guess you could include it for now. I'm still not happy with the size of the article, but if size is not a concern, I can see why it should be included.

The rate of CRI was highest in the medical mask arm (98 of 572; 17%); followed by the targeted N95 arm (61 of 516; 11.8%); and lowest in the N95 arm (42 of 581; 7.2%) (P < 0.05).
