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

The gastrointestinal side effects of Kayexalate administration are well-established, and despite its discontinued use in the United States, it is still important to consider in the clinical and pathologic differential, given the vast time range between administration and clinical presentation. One less common, though significant, complication of Kayexalate use is the formation of a malignancy-mimicking mass or pseudotumor. This presentation has been reported several times both within and outside of the gastrointestinal tract. Here we describe the case of a 65-year-old female presenting with a mass medial to the ascending colon with extension to the abdominal wall and adjacent bowel concerning for metastatic malignancy. Additionally, we review the current literature on Kayexalate associated pseudotumors and malignancy-mimicking masses.
