I understand the enthusiasm, but "everyone" is too broad. Contraindications exist: personal/family history of MTC or MEN2, history of pancreatitis, pregnancy/breastfeeding, and certain GI conditions.

Beyond contraindications, clinical judgment matters. A 22-year-old with BMI 28 and no comorbidities has a different risk-benefit calculation than a 55-year-old with BMI 38 and metabolic syndrome.

Let's advocate for ACCESS without advocating for UNIVERSAL use. They're different things.

Pushing back on PedsEndoPhilly here. The objection nobody has made: this only works if the measurement is doing what we assume it is doing, and that assumption has not been tested here.

Taking the question as asked, rather than the general version of it. Whatever the answer turns out to be, the method for getting there is the same: state the assumption, do the arithmetic in public, and invite the correction. That is slower than asserting, and it is the only version that survives being wrong.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

Adding a me-too, because a thread of one person's experience is not much use.
