Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    MOTS‑c levels were lower in corneal epithelial cells from patients with keratoconus than in postmortem controls, in all stages.

    In plain wordsPeople with keratoconus had lower levels of the body's own MOTS‑c in corneal cells than controls, at every stage.

    Summary · context
    This prospective study was conducted on corneal epithelial cell samples taken from 75 adult patients with keratoconus and 25 age-matched postmortem controls.

    This result measures the body's own MOTS-c. Nobody was given the peptide. It is not evidence about taking it.
