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

Background: Ureteropelvic junction obstruction (UPJO) is a frequent cause of congenital hydronephrosis. It involves both structural and functional changes at the ureteropelvic junction (UPJ), where the ureter connects with the renal pelvis. The mechanisms behind tissue remodeling and fibrosis in this condition are not fully understood. This study explores the role of epithelial-mesenchymal transition (EMT) and examines how receptor for activated C kinase 1 (RACK1) may regulate this process in UPJO. Methods: Stenotic UPJ tissues were collected from patients with congenital UPJO and analyzed for EMT and RACK1 expression. An Results: EMT features, including increased expression of N-cadherin, β-catenin, Vimentin, and ECM-related proteins (COL1A1, FN1, α-SMA), and decreased E-cadherin expression, were observed in both UPJO tissues and TGF-β1-treated cells. RACK1 was significantly upregulated in stenotic tissues and after TGF-β1 stimulation. RACK1 knockdown suppressed Smad2/3 and p65 activation, inhibited EMT features, and reduced cell proliferation and migration. Conclusions: EMT features are associated with tissue remodeling and fibrosis in congenital UPJO. RACK1 promotes TGF-β1-induced EMT through activation of Smad2/3 and p65 signaling. These findings provide new insights into the pathogenesis of UPJO and suggest RACK1 as a potential target for therapeutic intervention.
