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

Radical cystectomy is the most commonly used definitive local treatment for muscle-invasive bladder cancer (MIBC), yet it carries substantial perioperative complication risk, alongside major changes in urinary and sexual function. Chemoradiotherapy (CRT) is used as a bladder-sparing alternative but is usually reserved for small, solitary tumors. Highly active systemic induction therapy could enable bladder preservation for patients with more advanced tumors and reduce recurrence risk. We previously demonstrated high activity of preoperative ipilimumab (3 mg kg
