⚠️ Despite all the hype, chatbots still make terrible doctors. Out today is the largest user study of language models for medical self-diagnosis. We found that chatbots provide inaccurate and inconsistent answers, and that people are better off using online searches or their own judgment.

There are probably many benefits of sharing clinical trial data, including:
Verifying results, better meta-analysis, understanding inconsistent results, further exploration, better clinical decision-making, learning how to run trials better, and reducing redundancy.

The case for sharing clinical trial data
The story behind the first statin and how its development was almost derailed, and the implications of sharing clinical trial data.

I hate this: "The Editors have retracted this article... the Mini-Mental State Examination (MMSE) instrument was used without proper permissions" link.springer.com/article/10.1... The MMSE is a series of 11 simple questions. A perfectly good paper is retracted because you can copyright 11 questions

The Iowa Gambling Task is an extreme example of Jingle Fallacy and schmeasurement.
In 100 articles we found 244 different ways of scoring it, 177 were never reused. Correlations between them range -.99 to .99.
At the same time, we show meta-analyses combine these results as if they’re equivalent.

How many versions of the Iowa Gambling Task (IGT) exist? And how much does this affect research using the IGT? More than you might think. 🧵
