How do I read a cagrilintide chromatogram from Janoshik beyond the headline number?

Setup, so nobody has to ask: cagrilintide · Janoshik.

I can parse the result. I am less sure what it licenses me to conclude.

I have deliberately not looked at anyone else’s interpretation yet.

Which parts of this are informative and which are decoration?
