If you’ve been following the RFK Jr autism news, then you’ve probably heard that there’s a systematic review “proving” Tylenol causes autism.

Here’s my review of that paper👇🏼

The best evidence Tylenol causes autism isn't great
On Monday, RFK Jr announced Tylenol ‘causes’ autism referencing three studies as evidence. Let's dive in.

Some of these people have now been fired and rehired TWICE since January. The current state of dysfunction is mind boggling.

OOOPS! UPDATE: Two HHS officials tell me that disease detectives, measles response officers, global health officials and the MMWR staff were laid off by mistake and will be reinstated. But Washington office is still RIFed

BREAKING: Friday night massacre underway at CDC. Doznes of "disease detectives," high-level scientists, entire Washington staff and editors of the MMWR (Morbidity and Mortality Weekly Report) have all been RIFed and received the following notice:

“Workers continued to see elevated health-related absences linked to COVID-19…

[which] has likely raised the value to workers of paid-leave policies & existing social safety net programs.

Measures to reduce COVID-19 transmission in the workplace may also mitigate these new exposure risks”
Enduring Outcomes of COVID-19 Work Absences on the US Labor Market
This cohort study examines the extent to which COVID-19 continues to generate work absences and decrease labor force participation beyond the pandemic period in the US.

This is a massive deal. But it’s not a done deal. Workers have been barred from their offices, but there is still time to protect their jobs. Only your Reps can do it though. Don’t let up!

RIFs at CDC.

Destroying the Epidemic Intelligence Service, NCIRD, NCIPC & a dozen other areas/divisions/branches will cause enormous harm and suffering to America, and indeed to the whole world.

Call your Reps about it.

Then call them again.

One of those 2 circumcision-autism papers is an ecological study which is just about the worst study design they could have used for a question like this.
epiellie.bsky.social
Yup. It’s complete and utter nonsense.
epiellie.bsky.social
Adding them to the list, I guess. Still planning to do the big Swedish paper next though. We deserve to read something good

RFK Jr on Tylenol and autism: "It is not proof. We're doing the studies to make the proof."

😫😫😫But I literally just finished reviewing the papers! Ugh gotta do these I guess

If Sunday's summary left you hungry for more, today I've posted the full 20 minute read of all my thoughts about this paper.

It’s easy to miss the errors in papers like this because the problems are hidden in the things they don’t say. That’s how papers like this get through peer-review so often too.
epiellie.bsky.social
Basically, they used some data that had already been collected for a different reason, and then failed to do any sort of sanity checks on whether it was appropriate to use or not.
epiellie.bsky.social
That would certainly have been the first question I asked if this were my data. They don’t mention it.
epiellie.bsky.social
Yes exactly. I dont wanna sound like a hater, but I gotta point out the flaws!

My review of the third autism-Tylenol study RFK Jr mentioned is out now.

If you weighed in on "what proportion of kids have neurodevelopmental disorders" yesterday, this paper is why I asked the question. Most of you will be very surprised by their answer!

RFK Jr's third Tylenol-autism study is just run-of-the-mill bad research
I’m reading through RFK Jr’s supposed evidence that Tylenol causes autism and it’s not looking good for his conclusions.

I struggled to write this, because there are so many things wrong with this paper. They are all things that you see frequently in low-quality research, and it was hard to decide what to focus on.

Even real trials have an ideal target trial

The thing that’s really concerning about this paper is that the author team *looks* like they should know better. And yet.
