Objective:

To investigate the relationship between oxidative balance, systemic inflammation, and all-cause mortality in patients with rheumatoid arthritis.

Approach:

Key Findings:

• Each 1-point increase in oxidative balance score was associated with a 4% lower mortality risk.
• Patients with higher oxidative balance scores had a 37% lower mortality risk compared to those with lower scores.
• Each 1-unit increase in systemic inflammation response index was linked to a 14% higher mortality risk.
• Patients with high systemic inflammation and low oxidative balance had the poorest survival outcomes.
• Mediation analysis indicated that improved oxidative balance may reduce mortality risk by attenuating systemic inflammation.

Interpretation:

The study suggests that enhancing oxidative balance may be beneficial for reducing mortality risk in rheumatoid arthritis patients, particularly those with elevated inflammation levels.

Limitations:

• Oxidative balance and inflammatory status were measured at a single time point.
• Potential measurement error due to reliance on 24-hour dietary recall data.
• Diagnosis of rheumatoid arthritis was based on self-report, which may introduce bias.
• Residual confounding cannot be excluded, and the observational design limits causal inference.

Conclusion:

The findings highlight the importance of oxidative balance and systemic inflammation in mortality risk among rheumatoid arthritis patients, suggesting potential avenues for risk stratification and management.
