Diagnostic efficacy of high-frequency ultrasound and X-ray contrast enema in colonic strictures after necrotizing enterocolitis: a retrospective study.
Article in Pediatric surgery international, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo compare the efficacy of high-frequency ultrasound and X-ray contrast enema in the diagnosis of colonic strictures after necrotizing enterocolitis.
methodsThis study included pediatric patients who developed progressive abdominal distension or constipation after conservative treatment for necrotizing enterocolitis at our hospital between June 2012 and April 2020. All patients had high-frequency ultrasounds and X-ray contrast enema, and we used surgery, pathology, and telephone return visits as the reference standard. Patients with colonic strictures were confirmed by surgery and pathology. A patient was considered without colonic stricture if no stricture was reported or did not have related symptoms during telephone return visits. The areas under the Receiver operating characteristic (ROC) curves were used as evaluation indexes to compare the differential efficacy of high-frequency ultrasound and X-ray contrast enema.
resultsA total of 81 patients have been included in this study. Among them, 49 patients were diagnosed with colonic strictures after necrotizing enterocolitis. The AUCs for high-frequency ultrasound and X-ray contrast enema were 0.990 vs 0.938, respectively (p > 0.05).
conclusionThe diagnostic efficacy of high-frequency ultrasound was similar to that of X-ray contrast enema, furthermore this study also demonstrates the benefits of using high-frequency ultrasound to identify colonic strictures after necrotizing enterocolitis.
