DataDave said:The dose-response is real but shallow at the top.
Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. The trial means are being read too generously in this thread. STEP populations were selected, supported, and titrated by protocol, and the real-world curves are consistently a few points worse. That difference is not noise, it is what happens when you remove the study infrastructure.
One concrete data point for the thread. Worth knowing that the injection site changes very little. Abdomen, thigh and upper arm are bioequivalent for semaglutide, so a site change is not a plausible explanation for a bad week.
MikeFit_NJ said:The trial means are being read too generously in this thread.
Coming at MikeFit_NJ’s question from a different direction. FLOW is the relevant trial and it reported a meaningful reduction in kidney-disease progression and related death in people with type 2 diabetes and chronic kidney disease. The mechanism looks to be a mixture of reduced albuminuria, better glycaemia and blood pressure, and a probable direct anti-inflammatory effect on the glomerulus. Separately, eGFR is genuinely noisy during rapid weight loss — a small early dip is common and usually haemodynamic rather than damage.
Worth separating that from renal function, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

How to read eGFR during rapid weight loss, given that creatinine depends on muscle mass and muscle mass is changing?
OP back with an update, since a thread like this is useless without one.
Following this thread I went back and re-read the extension data properly. The point about trough rather than peak explains the pattern I was seeing on day six, which I had been blaming on the vial.
