Importance of very low proteinuria levels in immunoglobulin A nephropathy: evidence of a non-linear association with long-term kidney survival

Abstract Background Proteinuria is a major predictor of disease progression in immunoglobulin A nephropathy (IgAN), and lower levels are associated with more favorable kidney outcomes. Prior studies have largely evaluated proteinuria using predefined categories (e.g., < 0.5 g/d;...
