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.
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
backgroundAs esophageal gastrointestinal stromal tumors (GISTs) are very rare, their clinicopathological features remain obscure. We conducted a nationwide survey to clarify the characteristics of these tumors and to establish a consensus on their diagnosis and treatment.
methodsThe clinicopathological information of patients with esophageal GISTs who underwent treatment between January 2010 and June 2016 at the accredited institutions by the Japan Esophageal Society was collected via a questionnaire method and analyzed statistically.
resultsFifty-one patients (29 men and 22 women; median age, 68 years) were recruited from 31 institutions. Diagnosis was triggered most frequently during screening and other disease scrutiny. Symptoms were seen only in 17 patients: highest in 11 patients with dysphagia. Thirty-five patients underwent surgery alone; 15 patients, surgery with imatinib therapy; and one patient, endoscopic resection. The tumors preferentially occurred in the lower and middle parts of the thoracic esophagus, with a median size of 36.5 mm. Neoadjuvant and adjuvant imatinib therapies were performed in seven and eight patients, respectively. Administration of imatinib 400 mg/day was the standard regimen. Postoperative follow-up observations were conducted mostly via computed tomography (CT) scans every 3 or 6 months until 5 years after surgery. The tumors recurred in ten patients within 5 years postoperatively (high risk, 38.5%; intermediate risk, 20%; low risk, 0%; very low risk, 0%; three cases of relapse with an unknown risk assessment). A patient with a high-risk GIST died from the tumor 54 months after surgery.
conclusionsThis nationwide survey revealed the current status of esophageal GISTs in Japan and provided important information for making a consensus on the treatment and follow-up method.
