Association between red cell distribution width-albumin ratio and osteoarthritis in middle-aged and older adults: Analysis of NHANES data (1999-2018)

Key Points

• Osteoarthritis is significantly associated with elevated red cell distribution width-albumin ratio.
• Participants with high ratios showed a 25% increase in the prevalence of osteoarthritis.
• Analysis of NHANES data highlights correlations of biomarkers with osteoarthritis risk in older adults.
• Further exploration of these biomarkers could enhance early detection and treatment of osteoarthritis.
