The Guardian: 'Ultra-processed food linked to harm in every major human organ, study finds' "Evidence reviewed by 43 of the world’s leading experts suggests that diets high in UPF are linked to overeating, poor nutritional quality and higher exposure to harmful chemicals and additives. A...

Ultra-processed foods and human health: the main thesis and the evidence Summary This first paper in a three-part Lancet Series combines narrative and systematic reviews with original analyses and meta-analyses to assess three hypotheses concerning a dietary pattern based on ultra-processed...

So I think the association is: measure the peak VO2 after a single exercise test, and measure NEGR1 in the plasma immediately after the exercise. In people with ME/CFS, the higher the VO2, the higher the NEGR1. And in controls, the correlation was not significant. I'm hesitant to put too much...

See this post discussing a talk from the 2025 Portugal conference about this study:

Authors responded: They didn't say anything about the commenter's main point - that the pre-selected minimum important difference was not achieved.

What do you mean by them claiming they are equal? Aren't they claiming they are not equal based on their results?

Wow, I'm surprised how critical this is. I mean, we're talking about €3 million, so it's good to make sure the trial design is sound. But is it typical to take issue with so many parts of a protocol? I put the image into OCR to turn into text for easier reading, and added line breaks:

The Central Role of Macrophages in Long COVID Pathophysiology McMillan, Philip; Turner, Anthony; Uhal, Bruce [Line breaks added] Abstract This review article attempts to provide a unifying hypothesis to explain the myriad of symptoms and predispositions underlying the development of PASC...

It's a very strange system we currently have. The authors doing the science have to pay to publish. And the people reading the science have to pay. The peer-reviewers don't get paid for their help making money for the publisher. I don't know what value a publisher adds that can't be provided by...

Absolutely. Authors often reply, and sometimes get into spirited debates.

I think Pubpeer is kind of an in-between. It's considered fairly reputable because a large amount of comments about image manipulation and other issues have been posted about on there and led to retractions. But it's not officially attached to any journal, just a non-profit. While it might be...

The thing is, unless governments make laws saying you can't criticize a study on the internet unless you have uploaded an ID, which sounds ridiculous to me, it can't practically be achieved. If S4ME and Pubpeer take the initiative and somehow require your real name, then people will just start...
