1 · What the graph read from it

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.

2 · The registry

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

IgA nephropathy (IgAN) is a major cause of late graft loss after kidney transplantation, yet evidence for newly approved IgAN-specific therapies in this setting is scarce. We report a young male transplant recipient with biopsy-proven recurrent IgAN 7 years after living-donor transplantation. Treatment with targeted-release budesonide (Nefecon) was associated with a delayed and incomplete antiproteinuric response, clinically relevant systemic glucocorticoid-related adverse effects and progressive graft function decline. After discontinuation of Nefecon, combined therapy with Sparsentan and empagliflozin resulted in sustained albuminuria reduction, stabilization of graft function, improved blood pressure control, and resolution of metabolic complications. This case highlights challenges and opportunities in integrating novel IgAN therapies into post-transplant care.
