Description:
A major meta-analysis published in The Lancet made headlines claiming that “almost all” feared side effects of statins aren’t actually caused by statins—and the internet ran with it. In this video, I take you inside the actual data and show why those confident headlines don’t match the results. We’ll break down how to read the study’s key graphs, what “non-significant” does and doesn’t mean, and why “not proven” is not the same as “proven false.”
Then we’ll look at the blind spots and limitations that matter for real-world decisions. I’ll also address common pushback—like fears of “fear-mongering” and the argument that “statins save lives”—and explain why the ethical core here is informed consent: clear communication of uncertainty, signals, and tradeoffs. If you want deeper nuance, extra references, and a written breakdown, check the links above.
