Neural and central mechanisms of kidney fibrosis after relief of ureteral obstruction.
Article in iScience, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Obstructive uropathy from nephrolithiasis remains a leading cause of end-stage kidney disease. Mechanisms of kidney fibrosis after relief of ureteral obstruction represent opportunities for therapeutic intervention. Here, in mouse models of ureteral obstruction, we have combined methods of virus tracing and optogenetic techniques to identify an overactive central pathway in the paraventricular nucleus (PVN)-rostral ventrolateral medulla (RVLM) that determines the fibrotic fate of kidney after relief of the obstruction. The overactive pathway is driven by kidney afferent nerves that activate angiotensin II signaling in RVLM-projecting PVN neurons to drive sympathetic discharge back to the kidney. This causes the kidney to undergo fibrosis with loss of function. Blockade of sympathetic traffic or deletion of AT1a in PVN preserves the structure of the post-obstructed kidney. Human post-obstructed kidneys also demonstrate evidence of increased sympathetic nerve activity associated with a fibrotic outcome. Manipulating these neural elements is a potential treatment strategy.
