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: Primary malignant melanoma of the bladder (PMMB) represents an extraordinarily rare diagnostic entity among bladder malignancies, with fewer than 50 well-documented cases reported in modern medical literature. Due to its rarity, standardized treatment protocols remain undefined, and prognostic outcomes are poorly characterized. Case presentation: A 65-year-old man presented with a primary complaint of urinary tract irritation symptoms and an occupying lesion on the bladder wall detected during an enhanced CT scan. He underwent partial cystectomy and left ureterovesical reimplantation, and pathological results confirmed the diagnosis of PMMB. The prognosis was favorable, with no recurrence observed during a 24-month follow-up. Additionally, a comprehensive literature review was conducted to elucidate the typical characteristics and current therapeutic approaches reported to date, as evidence-based guidelines have yet to be established. Conclusion: Although PMMB is a rare bladder malignancy, certain similarities in its clinical and imaging features have been observed among the reported series. This study provides an additional summary of the tumor's biological characteristics while discussing current treatment paradigms, future perspectives, and potential therapeutic strategies.
