Comparison of detection frequencies between ultrasonography and abdominal radiography for abnormal signs in necrotizing enterocolitis: a systematic review and meta-analysis.
Article in Frontiers in pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To synthesize the existing evidence regarding the differences between abdominal ultrasound (AUS) and conventional radiography in detecting necrotizing enterocolitis (NEC) features in neonates. Methods: A six-database literature search was conducted to identify relevant English-language studies published prior to April 1, 2026 comparing the detection frequencies of AUS and abdominal x-ray (AXR) for imaging signs of neonatal NEC. Results: Twenty studies were identified that systematically compared the detection frequencies of AUS vs. AXR for detecting specific NEC features ( Conclusions: AUS and AXR show different patterns of detection of abnormal signs in NEC, with the former detecting portal gas and pneumatosis intestinalis more frequently than the latter. Combining the two modalities in clinical practice may facilitate earlier recognition and assessment of disease progression in neonatal NEC cases.
