Case Report: Maximizing the anti-proteinuric response: a multicenter real-world sparsentan case series in IgA disorders.
Article in Frontiers in nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Immunoglobulin A Nephropathy (IgAN) is a prevalent form of glomerulonephritis that leads to chronic kidney disease (CKD), typically marked by ongoing proteinuria, even when treated with standard therapies such as renin-angiotensin-aldosterone system (RAAS) blockers and occasionally immunosuppression. Proteinuria is a modifiable risk factor crucial for disease advancement. Sparsentan, a dual endothelin receptor and angiotensin receptor blocker (DEARA), has been introduced as a novel therapeutic option focusing on proteinuria. We present a case series featuring seven patients - five diagnosed with IgAN and two with IgA vasculitis (IgAV) - with severe proteinuria who were treated with Sparsentan, sometimes in combination with other medications such as targeted-release formulation (TRF) budesonide, sodium-glucose cotransporter-2 (SGLT2) inhibitors, or mycophenolate. Notable reductions in proteinuria and improvements in blood pressure regulation were observed in these cases. Sparsentan was well-tolerated overall, with no significant hyperkalemia or hepatotoxicity reported in this group. These cases emphasize the real-world experience, promising efficacy and safety of Sparsentan in reducing proteinuria in patients with IgA-mediated glomerular disorders, including its application in combination therapies and patients with concurrent or prior immunosuppression.
