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

Malignant tumours within the nipple-areola complex (NAC) should be considered when a non-healing, bleeding, or painful unilateral lesion persists. We report the unusual case of an 81-year-old male with prior melanoma and non-melanoma skin cancers who presented for a 1- to 2-year history of a painful lesion on the left nipple. On examination, there was a pink, crusted, tender, indurated papule within the left nipple without underlying breast masses or axillary lymphadenopathy. Histopathology revealed nodular basal cell carcinoma (BCC). The patient also had suspicious pulmonary nodules, which demonstrated metastatic melanoma. Unexpectedly, the BCC rapidly grew. It was ultimately treated with Mohs micrographic surgery. This case highlights the importance of maintaining a high index of suspicion for malignant tumours in atypical areas like the NAC, especially unexpected tumours such as BCC. Within the NAC, tumours may display more aggressive features, be misdiagnosed or undiagnosed until later stages, or inadequately treated.
