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

BACKGROUND Malignant peripheral nerve sheath tumor (MPNST) with pure epithelioid histology MPNST (epithelioid-MPNST) is a distinctly rare variant of MPNST described by World Health Organization. Occurrence of MPNST in the tubular gut is extremely rare with nearly 20 cases reported in the last 40 years. CASE REPORT In this case report, we described 2 such cases of epithelioid-MPNST occurring in a 65-year male and 47-year-old female, who both presented with bleeding rectal polyps. We also report on our comprehensive systematic literature review. CONCLUSIONS To the best of our knowledge, these are possibly the first two cases of pure epithelioid-MPNST at an unusual site. This needs to be differentiated from lesions more commonly encountered at the related anatomical site, such as malignant melanoma, poorly differentiated carcinoma, lymphoma, or even a gastrointestinal stromal tumor, by appropriate panel of antibodies.
