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

Introduction: Secondary extramammary Paget disease (EMPD) is a rare cutaneous malignancy that typically manifests on apocrine-rich skin originating from an underlying adenocarcinoma. It has a low chance of further metastasizing and treatment is recommended. Case Presentation: We present a case of an 86-year-old man with a history of bladder carcinoma that was successfully treated and in remission for 4 years, who developed an asymptomatic rash on the glans penis. Histopathology and immunohistochemistry confirmed secondary EMPD of urothelial origin. Cancer screening was negative and this was declared secondary EMPD without recurrence of primary malignancy. The patient declined surgical and pharmacologic treatment. After 1 year, the lesion spontaneously resolved with no recurrence. Conclusion: Secondary EMPD can present without underlying malignancy and may spontaneously regress. This is a rare phenomenon and the mechanism is not yet known. We speculate that it may be related to adaptive immunity, local inflammation promoted by biopsy and that there was no underlying primary malignancy. Treatment decisions should be made in the context of thorough goals of care discussions. Further observation of this phenomenon is required to guide management plans.
