Flawed design and selection bias in critical care randomized controlled trials (RCTs): the patient safety risk of the "RCT mimic" - PubMed
Over three decades, randomized controlled trials (RCTs) for critical care syndromes such as acute respiratory distress syndrome (ARDS), sepsis, and community acquired pneumonia (CAP) have repeatedly produced non-reproducible results, at times leading to high-impact reversals of global protocols when …

I’m at the point where I think most sepsis (trial level) research is so fundamentally flawed that it is unlikely to show anything other that random noise. I don’t agree with everything Lawrence says, but he makes some extremely good points on this topic.

It’s hard to correctly state the contribution Richard has made to statistical education. He’s made the subject come alive for so many students (myself included) and continues to iterate and improve on what is already wonderful pedagogy: all for free. An inspiration to educators everywhere. 🤩🙏🎓
