What this study reported

Found higher plasma MOTS-c and SHLP2 in participants with metabolic syndrome, with positive associations across blood pressure, fasting glucose, triglycerides and, most strongly, waist circumference. Android fat and specifically liver fat were positively associated with plasma MOTS-c, and levels were also higher in participants with raised liver damage markers and in mice fed a diet causing hepatic lipid accumulation.

Limitations

Cross-sectional design in a single predominantly male Chinese sample with a small separate female comparison group; MRI/S substudy is limited to women, and the mouse component uses one strain and sex.

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.
