Shared outcomes
From the regulatory data of each peptide.
Outcome groups with study results for at least two of these peptides. Counts include only results from studies that gave the peptide. Bar length is the number of results, on one scale. The bars show how much was studied, not how large an effect was. A peptide with more studies can look stronger here without being stronger. For results, see the randomized results above.

For each outcome that two or more peptides have results for: the best result of a single randomized trial, on the same measure (the same kind of number, the same unit). When a trial has several dose arms, the cell shows the highest dose arm. The trials differ in people, length and dose, so a gap between two cells is not proof that one peptide works better.
No outcome has a randomized-trial result on the same measure for two or more of these peptides yet.
The other peptides have no randomized result on the same measure, so these results cannot be set side by side.
