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
Background and objective: Management of long proximal ureteral strictures remains a significant challenge. Posteriorly augmented anastomotic ureteroplasty with lingual mucosal onlay grafts (PAAU-LMG) is a novel technique used for treating obliterated or diseased ureteral segments. This study aims to evaluate the long-term effectiveness of PAAU-LMG in a multi-institutional cohort of patients with long, complex proximal ureteral strictures. Methods: This retrospective study involved data for 61 patients treated with PAAU-LMG at three centers between April 2017 and December 2024. Perioperative and follow-up data were collected. Surgical success is defined by the absence of clinical symptoms, no stricture on imaging, and no severe complications. A descriptive statistical analysis was performed. Key findings and limitations: Of the 61 patients, 18 underwent laparoscopic surgery and 43 underwent robotic surgery. PAAU-LMG was performed in 45 (73.77%) cases, 16 (26.23%) cases underwent PAAU-LMG with ureteral dorsal adventitia "fold" technique. The reconstructed ureter was covered with perirenal fat in four cases (6.56%) and with omentum in 57 cases (93.44%). The median (range) stricture length was 3.60 (1.50-9.00) cm, operative time was 140 (84-306) min, estimated blood loss was 50 (10-400) ml, and postoperative hospital stay was 6 (4-10) d. No open conversions and intraoperative complications occurred. At a median (range) follow-up of 32 (7-98) mo, the overall success rate was 100% (61/61). The main limitation is the lack of a control group. Conclusions and clinical implications: PAAU-LMG is a safe, effective, and feasible treatment for selected patients with long obliterated or diseased proximal ureteral strictures. Patient summary: We evaluated the long-term follow-up outcomes of posteriorly augmented anastomotic ureteroplasty with lingual mucosal onlay grafts (PAAU-LMG), in which the diseased ureter was excised and reanastomosed primarily on the dorsal side, and a lingual mucosal graft was placed on the ventral side. For patients with obliterated or diseased ureter stricture, PAAU-LMG is a safe and feasible alternative with satisfactory outcome.
