An observational analysis linking a composite inflammation and nutrition biomarker to low muscle mass risk in rheumatoid arthritis patients and population validation.
Key Takeaways
- Patients with high NPAR showed significantly higher LMM prevalence than those with low NPAR
- NPAR demonstrated strong discriminatory ability (AUC = 0.80, optimal cutoff = 9.55)
- Additionally, higher NPAR was associated with increased all-cause mortality in RA patients with LMM during follow-up
