What this study reported

Measured circulating MOTS-c and humanin by ELISA in adults with COVID-19 before and during antiviral drug therapy and in healthy volunteers. Found higher serum MOTS-c and lower serum humanin in the COVID-19 group than in the control group, and reported no significant change in either peptide between the pre-treatment and post-treatment samples.

Limitations

Small single-centre sample of 30 patients; no reported adjustment for disease severity, comorbidity or concomitant medication, and the paired samples span only the first week of therapy with no untreated patient comparison.

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.
