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

Extramammary Paget's disease (EMPD) is a rare intraepithelial adenocarcinoma. EMPD can be associated with an underlying malignancy of an adjacent organ, in which case the skin lesion is known as the pagetoid spread (PS) of the underlying tumor. PS, also known as secondary EMPD, has a worse prognosis than primary EMPD. The standard treatment is surgery, but the efficacy of nonsurgical treatments is unknown in inoperable cases. We present 2 cases of anal canal adenocarcinoma with PS that were treated with definitive concurrent chemoradiation therapy (CCRT). Although both cases experienced recurrence outside of the radiation field, and one died, anal function was preserved in both. In conclusion, CCRT may be a viable treatment option for inoperable anal canal cancer with PS.
