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

Blue nevus is a benign dermal lesion occasionally associated with malignant transformation into melanoma arising in a blue nevus, a rare and aggressive form of melanoma with different molecular features. Fewer than 200 cases have been reported worldwide. In this case study, a 78-year-old woman presented with a congenital bluish nodular lesion on the left buttock that enlarged over the years. Magnetic resonance imaging suggested a malignant soft tissue tumor. Surgical excision was performed, accompanied by an intraoperative histopathological study, reporting a melanoma with no dermoepidermal junction involvement. Immunohistochemistry confirmed the melanocytic origin; molecular analysis ruled out a
