The combined impact of inflammation and oxidative balance on mortality risk in rheumatoid arthritis patients: A retrospective cohort study

Oxidative stress and systemic inflammation play pivotal roles in rheumatoid arthritis (RA) progression. However, the combined impact of oxidative balance and inflammatory status on mortality risk in RA patients remains insufficiently investigated. This study aimed to explore these potential associations. We analyzed data from 24,552 participants in the National Health and Nutrition Examination Survey (NHANES, 2007-2018). Oxidative balance was assessed using the oxidative balance score (OBS), whi
