What was studied?
A pilot study measured MOTS-c in serum, urine and dialysate from thirty-two stable peritoneal-dialysis patients.
What did the researchers report?
Associations differed by compartment. Urinary levels correlated with both lower oxidative-stress markers and greater arterial stiffness, while dialysate levels showed a different vascular pattern.
What are the limits?
Small observational correlations do not identify cause or indicate that supplementation helps. Renal handling and sampling compartment are important alternative explanations.
