This study leverages the global Dialysis Outcomes and Practice Patterns Study (DOPPS) database to generate real-world evidence on the burden of IgAN in patients who progress to kidney failure and require maintenance hemodialysis (HD). We will first aim to understand prevalence of IgAN in a global cohort of in-center HD patients. The second and third objectives aim to quantify the patient burden of IgAN using a two-step approach: first, a detailed single-arm evaluation of outcomes within the IgAN population; second, a matched comparison to the broader HD population.
