Association between rheumatoid arthritis and hyperuricemia among adults: a cross-sectional study based on NHANES data

RA was associated with hyperuricemia and their association was still stable even after adjusting for several variables, suggesting that uric acid levels should be routinely tested to detect hyperuricemia at an early stage in patients with RA. Key Points • Revealing association between rheumatoid arthritis (RA) and hyperuricemia risk: This study initially explored the association between RA and hyperuricemia, finding that RA was positively related to the higher uric acid levels and hyperuricemia risk. • Reflecting the role of RA course on their association: Our study found that their association was mainly observed in population with RA course of 15-30 years.
