SURMOUNT-1 was a 72-week trial in adults with obesity or overweight without diabetes. Mean body-weight change in the 10mg group was −19.5%. This was a controlled trial with defined participants, lifestyle intervention and follow-up, and it does not predict an individual result.

The chart visualizes group means reported in the paper. It does not predict an individual response at each dose.
The SURPASS program also evaluated tirzepatide doses including 10mg in people with type 2 diabetes. Obesity and diabetes trials have different populations and objectives, so their results should not be treated as interchangeable.
