What this study reported

Reviewed evidence that levels of mitochondrial-derived peptides, including MOTS-c, decline with age and relate to senescence, chronic inflammation and cognitive decline. Also summarised coding-region variants in MOTS-c and humanin reported to associate with age-related disease.

Limitations

Narrative review without systematic search; much of the cited MOTS-c evidence is preclinical or based on cross-sectional associations.

Appraisal

Each dimension is recorded separately and never combined into a single score. A study can be well controlled and still tell you little about people.
