It's quite remarkable watching the very minimal respect I had for Vinay entirely disappear.

The Guardian investigation into freebirthing is one of the most horrifying things I've read in a long time.

Just awful. So many preventable deaths.

I've come across a trial which randomized in blocks of 4 but had baseline allocations of 54 vs 35.

This does not seem possible to me. Am I missing something?

The stuff you find when you actually read the RCTs in a systematic review...

This paper is one of the foundational studies on vitamin D to prevent respiratory infections in kids. Cited 1,400 times as per Google Scholar.

Scientific error-checking, difficulty: easy

Find some issues in this table of results from an RCT of vitamin D for COVID-19. There's a couple of obvious issues, and some that are less easy to spot.

Every time I think that the story of vitamin D supplementation can't get any more ridiculous, it somehow does.

The most used pill in the world and we know it's probably a waste of time for most people.

My new piece is on the idea that Batman can make us more ethical and why it is very unlikely to be true.

Ah, Bryan Johnson: the man who looks a decade older than he is and has almost certainly harmed his health through a cocktail of useless - but harmful - supplements.

Also, he pays millions a year for the privilege. HEALTH.
And then there was Bryan Johnson, a Silicon Valley multimillionaire known for his extreme anti-ageing ‘biohacks’, like receiving plasma from his teenage son.

Johnson, on a quest to live forever, wants “competing for the best biomarkers of anybody in the world” to be something of a new sport.

Sad to see the CDC is now spreading fairly straightforward lies.
CDC has overhauled its website to assert that “the claim ‘vaccines do not cause autism’ is not an evidence-based claim”

Very interesting data - desk rejections have risen hugely at Frontiers journals due largely to paper mill detections and other fraud checks.

Do any other publishers do this automatically?

Potentially, LLMs lower the bar and allow the stupid ones to do a better job"

Systematic reviews are considered the cornerstone of medicine. But some of the eligible trials that could be included might be problematic. They could get included.

We end today's conference day with a discussion led by Gideon Meyerowitz-Katz @gidmk.bsky.social
Anyone who has tried to report concerns will have experienced how journals and institutions defer responsibility to the other party and how they 'investigate' and find 'no misconduct'.

I've thought for a while that one of the key parts of pandemic success - both in terms of mortality and economics - during COVID-19 was public trust.

I also think that one of the things that really supported public trust was consistency of messaging and implementation.

Someone asked me about ivermectin for COVID-19 recently and it's such a bizarre blast from the past.

Can't believe it's been more than 4 years since we proved much of the benefit was based on fraudulent research! Wild.

It is so bizarre seeing people argue that the incredibly limited data showing that severe cases of Long COVID have some minor immune issues makes COVID-19 anything like HIV.

Imagine getting headshot by a 14 year old in Arc Raiders and then you report him to the Australian police who ban his account. Incredible. Incredible feeling.
Tbh they should include all such platforms in the ban, it would save me from being owned by 14yos.
