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

Anorectal melanoma is a rare and aggressive neoplasm with a poor prognosis; the overall survival rate at 5 years is around 20%. We report two clinical cases involving patients who experienced pain and bleeding associated with an anorectal mass. Histopathological studies confirmed the diagnosis of melanoma. The first case presented with localized disease characterized by a black, pedunculated lesion with irreducible prolapse managed with wide local excision. In the second case, the patient had a fixed, pink anal lesion accompanied by multiple inguinal and retroperitoneal lymphadenopathies. Due to the metastatic nature of the disease, immunotherapy was administered. Both patients remain alive after 1 year of follow-up.
