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
purposeThis study aimed to evaluate the diagnostic performance of ultrasound to locate atresia/stenosis and other abdominal anomalies in pediatric patients with duodenal atresia/stenosis, including intestinal malrotation and annular pancreas.
methodsWe classified 36 retrospective cases of duodenal atresia/stenosis based on intestinal malrotation status, and evaluated the diagnostic performance of ultrasound/upper gastrointestinal contrast studies to locate atresia/stenosis and intestinal malrotation, as well as ultrasound for detecting additional anomalies such as annular pancreas. The incidence of annular pancreas was compared between groups using Fisher's exact test.
resultsAtresia/stenosis was correctly located by ultrasound in 33 (91.7%) cases and by upper gastrointestinal contrast study in 36 (100%) cases. Of the eight cases with intestinal malrotation, five and two were correctly diagnosed by ultrasound and upper gastrointestinal contrast study, respectively. Ultrasound correctly diagnosed annular pancreas in 6/14 cases. The incidence of annular pancreas was significantly different between the groups (present/absent in groups with vs. without intestinal malrotation: 6/2 vs. 8/20, P = 0.036).
conclusionsUltrasound has a relatively high capability in locating atresia/stenosis. However, some cases are misdiagnosed. In clinical practice, upper gastrointestinal contrast studies should be used complementarily during diagnosis. Additional anomalies may not be detected by preoperative examinations; therefore, surgeons should carefully evaluate for additional anomalies during surgery, especially coexisting intestinal malrotation and annular pancreas.
