Another day, another viral article being cited as proof that ivermectin can cure COVID-19
The newest example is even more depressing than previous ones somehow 1/n
2/n The paper is here, and mostly it's just a perspective piece in a minor Nature offshoot (Journal of Antibiotics, IF 2.4) written by two members of what I can only describe as a pro-ivermectin advocacy group nature.com/articles/s4142…
3/n The advocacy group is called Front Line COVID Critical Care Alliance, and has a very flashy website that basically advocates for ivermectin (and vitamin D, melatonin, and mouthwash) as the cure of all COVID ills
4/n Now, this might be something of a red flag for publication in a scientific journal, but this affiliation isn't mentioned in the paper or the conflicts of interest which is a bit odd
5/n The review itself is mostly fairly boring - it is a reiteration of the same lab-bench data that was used initially as a reason to trial ivermectin, although the language is quite strange at times ("unsuspecting victims" is, uh, quirky)
6/n But some parts of the piece are simply wild. For example, instead of citing the Cochrane, BMJ, or other recent systematic reviews, the authors cite ivmmeta dot com, an anonymous website that is far from scientific
7/n Indeed, the authors have copied the information in this paragraph directly from this shoddy website, leading to this wonderful sentence making its way into a published scientific paper
8/n Complete misinterpretations of p-values aside, the website is one of many really bizarre anonymous efforts to push ivermectin and other unproven medications for COVID-19
9/n More rigorous reviews have pointed out that virtually all published studies on ivermectin are of extremely low quality, but you wouldn't know that from the summary presented on ivmmeta dot com!
10/n In fact, one of my favourite parts is where a WHO investigation that concluded that ivermectin should not be given outside of a clinical trial as the evidence is so woeful is misrepresented as showing that ivermectin is massively beneficial!
11/n (As a side note, the odds ratio is apparently presented because the WHO didn't "provide the details required to calculate the RR". That's weird, because the WHO did in fact calculate an RR in the report)
12/n Anyway, this website is what I would call solidly pseudoscientific - mimicking science closely enough to trap the unwary, but so filled with errors that the evidence is largely worthless
13/n Even funnier than all this, perhaps, is the conclusion of the paper, because despite this all being used online as proof that ivermectin works perfectly that's not even what the authors say
14/n I mean, "repurposing of approved drugs such as ivermectin" has been the focus of most of our attention since March 2020, it's not like we needed that push
15/n Anyway, it is very odd that this paper was published as is, it has at least a few pretty bizarre red flags, but that hasn't stopped it reaching an Altmetric of 4,500
Yay, science!

The final large published trial on ivermectin for COVID-19, PRINCIPLE, is now out. Main findings:
1. Clinically unimportant (~1-2day reduction) in time to resolution of symptoms. 2. No benefit for hospitalization/death.
Now, you may be asking "why does anyone care at all any more about ivermectin for COVID?" to which I would respond "yes"
We already knew pretty much everything this study shows. That being said, always good to have more data!
The study is here:
For me, the main finding is pretty simple - ivermectin didn't impact the likelihood of people going to hospital or dying from COVID-19. This has now been shown in every high-quality study out there.pubmed.ncbi.nlm.nih.gov/38431155/
What's particularly interesting is a finding that the authors don't really discuss in their conclusion. These results appear to show that gender affirming care is associated with a reduction in suicide risk 1/n
2/n The paper is a retrospective cohort study that compares young adults and some teens who were referred for gender related services in Finland with a cohort that was matched using age and sex. The median age in the study was 19, so the majority of the population are adults.
3/n The study is very limited. The authors had access to the Finnish registries which include a wide range of data, but chose to only correct their cohorts for age, sex, and number of psychiatric appointments prior to their inclusion in the cohort.
These headlines have to be some of the most ridiculous I've seen in a while
The study tested 18 different PFAS in a tiny sample of 176 people. Of those, one had a barely significant association with thyroid cancer
This is genuinely just not news at all
Here's the study. I'm somewhat surprised it even got published if I'm honest. A tiny case-control study, they looked at 88 people with thyroid cancer and 88 controls thelancet.com/journals/ebiom…
Here are the main results. There was a single measured PFAS which had a 'significant' association with the cancer, the others just look a bit like noise to me
A new study has gone viral for purportedly showing that running therapy had similar efficacy to medication for depression
Which is weird, because a) it's not a very good study and b) seems not to show that at all 1/n
2/n The study is here. The authors describe it as a "partially randomized patient preference design", which is a wildly misleading term. In practice, this is simply a cohort study, where ~90% of the patients self-selected into their preferred treatment sciencedirect.com/science/articl…
3/n This is a big problem, because it means that there are likely confounding factors between the two groups (i.e. who is likely to choose running therapy over meds?). Instead of a useful, randomized trial, this is a very small (n=141) non-randomized paper
The study showed that COVID-19 had, if anything, very few long-term issues for children! As a new father, I find this data very reassuring regarding #LongCovid in kids 1/n
2/n The study is here, it's a retrospective cohort comparing children aged 0-14 who had COVID-19 to a matched control using a database of primary care visits in Italy onlinelibrary.wiley.com/doi/10.1111/ap…
3/ The authors found that there was an increased risk of a range of diagnoses for the kids with COVID-19 after their acute disease, including things like runny noses, anxiety/depression, diarrhoea, etc
This study has recently gone viral, with people saying that it shows that nearly 20% of highly vaccinated people get Long COVID
I don't think it's reasonable to draw these conclusions based on this research. Let's talk about bias 1/n
2/n The study is here. It is a survey of people who tested positive to COVID-19 in Western Australia from July-Aug 2022 medrxiv.org/content/10.110…
3/n This immediately gives us our first source of bias
We KNOW that most cases of COVID-19 were missed at this point in the pandemic, so we're only getting the sample of those people who were sick enough to go and get tested
