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
backgroundSport-related concussion (SRC) in rugby union is common and carries a high injury burden, especially among children. Computed tomography (CT) imaging is commonly used to assess rugby-related head injuries, including SRC, subjecting children to ionising radiation. In addition, there is concern about the relationship between SRC, repetitive head impacts and neurodegeneration.
objectiveTo review and correlate the imaging findings of head injuries in school-level rugby players from a public tertiary referral centre and a private multi-centre radiology service.
designDescriptive, retrospective cross-sectional correlational study for the 2014-2023 period.
methodsAnonymised data were collected from the radiological information systems of a tertiary referral centre and a private radiology provider. Data included participant age, imaging modality, study type, date, findings and SRC status. The public and private datasets were analysed using descriptive and comparative statistics.
resultsA total of 369 cases were identified (public n = 132, 36%). Mean participant age was 15 (± 2.5) years, with 78% (n = 289) clinically deemed to have an SRC. CT was performed in 347 (94%) cases, with abnormal findings reported in 50 studies (public n = 32). The most common findings were craniofacial fractures (n = 28) and intracranial injuries (n = 19). The sensitivity of CT for detecting SRC was 14%. Public sector participants were more likely to have an SRC (odds ratio: 8.39; 95% CI 8.37-8.41, p < 0.001).
conclusionsCT demonstrates limited utility in the context of SRC beyond detecting craniofacial fractures or surgical emergencies, reinforcing clinical assessment as the diagnostic cornerstone. Protocol optimisation should prioritise radiation risk mitigation through strict adherence to paediatric low-dose guidelines.
