Assessment
Primary outcomes Clinical performance for differentiating IgA nephropathy from other renal diseases by the combination of urinary glycan profiling and clinical tests (hematuria, proteinuria, serum IgA) (Sensitivity and Specificity)
Key secondary outcomes 1) Clinical performance for differentiating IgA nephropathy from other renal diseases by the combination of urinary glycan profiling and clinical tests (hematuria, proteinuria, serum IgA) (Accuracy and ROC-AUC)
2) Clinical performance for differentiating IgA nephropathy from other renal diseases by urinary glycan profiling (Sensitivity and Specificity)
3) Clinical performance for differentiating IgA nephropathy from other primary glomerular diseases by the combination of urinary glycan profiling and clinical tests (hematuria, proteinuria, serum IgA) (Sensitivity, Specificity, Accuracy, and ROC-AUC)
4) Clinical performance for differentiating the participants with IgA nephropathy from with other renal diseases in 4 subgroups defined by 2 factors, eGFR (>= or <30 mL/min/1.73m2), and proteinuria (>= or <0.5 g/gCr), by the combination of urinary glycan profiling and clinical tests (Sensitivity, Specificity, Accuracy, and ROC-AUC)
