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

Introduction: Kidney transplantation remains the preferred treatment for end-stage renal disease; however, the increasing use of extended-criteria donors has been associated with a higher incidence of postoperative complications. Methods: We retrospectively analyzed 471 kidney transplant recipients at the University of Cologne between 2012 and 2022 to evaluate the incidence, risk factors, clinical outcomes, and surgical management of ureteral stenosis. Results: Ureteral stenosis occurred in 6.37% and was significantly associated with older donor age within the extended-criteria donor range (65 vs. 56 years, p = 0.006), multiple renal arteries (33.3% vs. 10.2%, p < 0.001), and BK virus infection, as reflected by higher rates of BK viruria (26.7% vs. 7.0%, p = 0.002) and BK viraemia (26.7% vs. 8.6%, p = 0.005). Renal function was significantly impaired in recipients with ureteral stenosis at 6 months, 1 year, and 2 years after transplantation. Death-censored graft survival was significantly lower in the stenosis group (79.7% vs. 93.3%, p = 0.01). Discussion: Ureteral transposition and ureteroneocystostomy demonstrated comparable outcomes, long-term renal function and graft survival supporting individualization of surgical technique based on anatomical and patient-specific factors.
