What fraction of loss on tirzepatide is lean mass according to PIONEER-4?

For reference: tirzepatide · PIONEER-4.

I have the document in front of me and I can read the numbers. What I cannot do is interpret them.

I am reasonably comfortable with statistics and completely uncomfortable with chromatography, or vice versa.

What does this actually establish, and what does it not?
