Nice example to explore type M and S errors If we assume true effect is HR = 0.7: - 11% chance that the estimate is in the wrong direction - Magnitude of the effect is exaggerated by a factor of 5.2 If HR = 0.5 - S-type error= 1.5% - M-type= exaggerated by a factor of 2.8 code:

Very interesting distributions from a RCT of antibiotic. Bimodal peaking at 0 and ~7, while also truncated at 0 What distribution would fit this best?

✨ New open-access book✨ I’ve seen how powerful prediction models can be, but also how often they fall short. We wrote a book, covering not just development, but also when models are needed, and how to ensure real-world impact.

COULD EVERYONE PLEASE STOP USING RANDOM EFFECTS META-ANALYSIS WHEN COMBINING 3 OR 4 TRIALS? AND COULD REVIEWERS STOP DEMANDING IT?

Amazing work. I was particularly interested in visualizations for studies on dexmedetomidine for investigating dosage, timing, risk of bias. Vibe-coded this app:

Example visualization attached. code:

I'd love some feedback
