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.

Each analog against its native parent, residue by residue. Substitutions, non-standard residues and modifications are marked. Calculated from the two sequences.
LL-37 is the same as Cathelicidin antimicrobial peptide precursor (hCAP18) residues 134 to 170.
No differences in the aligned region.
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.
Registered trials, ranked by phase (late phases first), then posted results and enrollment. Status is the registry status. Study results come from published studies. Results posted at ClinicalTrials.gov are shown on each trial page.
