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

backgroundGastrointestinal stromal tumors (GISTs) are considered as rare gastrointestinal tumors, and their location in the anal track is exceptionally unusual. We describe the case of a 28-year-old man with anal GIST, and a review of the cases that have been reported so far in the literature. CASE REPORT: The patient was referred for treatment of a gradually enlarging perianal mass. Clinical examination and imaging including orthosigmoidoscopy, transanal ultrasound, and magnetic resonance imaging (MRI) revealed a mass sized 7.5 cm in greatest diameter, in relation with the sphincters, which was excised under general anesthesia. His postoperative course was uneventful and he was discharged on the fourth postoperative day. Pathologic examination revealed characteristics of anal GISTs and further treatment with tyrosine kinase inhibitors was planned.

conclusionAnal GISTs usually present with rectal bleeding and pain, and only sixteen cases have been reported in the literature. MRI is the radiologic examination of choice, while optimal treatment is considered surgery in combination with adjuvant therapy. Long-term follow-up is necessary. Hippokratia 2016, 20(4): 313-316.
