This is an example of the rot inside Nature.
This will be hyped and canonized as truth. Influencers will take over, and critical scientists will stay quiet or be left out of the conversation.
The topic is trendy, so it gets published, and the tacit conclusions are far more grand than what the data support. They are essentially claiming to have found a genetic basis of GLP-1 response.
In reality, this is a GWAS study. These studies rarely identify genes of real interest and have largely proven ineffectual in complex diseases, in part because these traits are multigenic and heavily influenced by environment. GWAS looks at single associations and says nothing about causality.
At first glance, the effect size is not even reported in the abstract. And the p-value of the lead hit—near the GLP-1 locus—given a cohort of nearly 30,000, strongly suggests the effect is very small and not much overall came from this study just like most of the GWAS studies conducted over the past 15-20 years.
A massive Nature study of 27,885 GLP-1 users just dropped some major news about Ozempic and tirzepatide.
