01 / DESIGN
What was studied?
Researchers compared lean and obese adults, with a small subset measured again after bariatric surgery.
02 / FINDINGS
What did the researchers report?
Circulating levels were higher in the obesity group and showed nonlinear metabolic associations. They did not clearly change after postoperative weight reduction in the follow-up subset.
03 / LIMITS
How should it be interpreted?
Only a small number had repeat measurements. Endogenous biomarker patterns do not demonstrate the effects of exogenous MOTS-c or establish a diagnostic threshold.
