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

Anal melanoma is a rare malignancy, accounting for 0.4% to 1.6% of all melanomas. Its atypical presentation, low incidence, and non-specific symptoms make it a challenging diagnosis, which can lead to delayed treatment with an unfavorable impact on clinical outcomes. Treatment should be multidisciplinary and may include surgical resection with adjuvant therapy, chemotherapy, and radiotherapy. We present the case of a male patient who presented to the emergency department due to foreign body sensation and transanal bleeding. The patient underwent an anal exploration under anesthesia, where a hyperpigmented canal-dependent tumor lesion with extension into the perianal skin was found. After a wide local excision, histopathological study confirmed the diagnosis of invasive nodular melanoma. The patient was discharged without complications for follow-up and management in the outpatient medical oncology clinic.
