An inverse dose-response relationship was found between hydroxychloroquine use and risk of incident CKD. Patients with rheumatoid arthritis and cumulative doses of hydroxychloroquine 70 defined daily dose had a significantly lower risk of CKD aHR, 0.37; 95% CI, 0.16 to 0.84; P =0.004 for trend Table 2.
