Pushing back on mike_nyc here. 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.
Worth separating that from the trial evidence, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.
