Nonlinear association between the composite dietary antioxidant index and kidney stone disease: Mediation by systemic immune–inflammatory status in a cross-sectional study
Objective Oxidative stress and inflammation have been implicated in kidney stone disease. The Composite Dietary Antioxidant Index (CDAI) reflects the combined intake of multiple dietary antioxidants, but its association with kidney stones and the potential statistical contribution of immune-inflammatory markers remain...
