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

purposeRobot-assisted radical cystectomy (RARC) is globally accepted, but single-surgeon, high-volume data linking perioperative factors with long-term oncologic outcomes are limited. MATERIALS AND

methodsWe retrospectively reviewed 304 consecutive RARC cases performed by one surgeon between 2007 and 2024. Total intracorporeal urinary diversion (ICUD) was used in 73.0% of patients and orthotopic neobladder (ONB) reconstruction in 64.5%. Median follow-up was 51.21 months. Primary endpoints were overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS). Secondary endpoints included complication profiles and pentafecta, defined as margin-negative resection, ≥16 or more lymph nodes, no Clavien-Dindo grade ≥3 or higher complication within 90 days, no recurrence within 12 months, and no ureteroenteric stricture.

resultsMean operative time was 447.61 minutes, median lymph-node yield was 31.0 in the extended PLND group and 24.0 in the standard PLND group, and the positive margin rate was 1.0%. ICUD was associated with shorter hospitalization than extracorporeal diversion (13.81 days vs. 17.03 days, p=0.026) and fewer early high-grade complications. Seven-year OS, CSS, and RFS were higher in pentafecta achievers (69.3%, 94.2%, and 82.6%), and 7-year OS was also superior in patients with organ-confined (≤T2) and node-negative disease (69.0% vs. 28.6% and 67.5% vs. 19.4%). Complications occurred in 59.7% overall, with 14.9% major; infections were most common (20.7%).

conclusionsIn a high-volume single-surgeon series, RARC with ICUD provided durable oncologic control, acceptable morbidity, and high pentafecta achievement. Pathologic T and N stage and pentafecta were significant prognostic indicators that may assist in refining patient selection, guiding postoperative surveillance, and informing survivorship care.
