Reduced hospitalisations for paediatric mild traumatic brain injury: a nationwide observational study.
Observational study in BMJ paediatrics open, 2025. 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
objectiveTraumatic brain injury (TBI) is common in childhood, with mild TBI (mTBI) predominating. Germany reports higher hospitalisation rates for paediatric TBI than any other country, suggesting overadmission of mild cases. The study objective was to determine TBI-related hospitalisations in patients <18 years from 2014 to 2020 and describe variability of TBI-related hospitalisations between emergency departments (EDs).
designRetrospective observational study using the German hospital dataset (GHD) and controlling data from 18 paediatric EDs.
settingCases were identified from the GHD using International Classification of Diseases-10 codes and classified by severity using the Abbreviated Injury Scale for the head. Additionally, the proportion of inpatient versus outpatient TBI management from 18 paediatric EDs was assessed. PATIENTS: Cases with TBI as discharge diagnosis hospitalised in Germany (GHD) or presenting at a participating ED.
interventionsN/A.
main outcome measuresStandardised morbidity ratios (SMRs) for 2020 with 2014-2019 as reference period (GHD); proportion of hospitalisations of TBI patients per ED.
resultsAmong 618 577 TBI cases, mean annual TBI hospitalisations declined from 91 299±1656 (mean±SD) cases in 2014-2019 to 70 783 in 2020. SMRs for all-cause admissions (0.83 (95% CI 0.81 to 0.85)) and mTBI (0.75 (95% CI 0.73 to 0.78)) decreased more strongly than for moderate and severe TBI (0.95 (95% CI 0.91 to 0.99) and 0.95 (95% CI 0.90 to 1.01)). Hospitalisation rates in EDs ranged from 19.1% to 93.0% (median: 75.0%). CONCLUSIONS AND RELEVANCE: The disproportionate reduction of mTBI hospitalisations during the COVID-19 pandemic compared with moderate to severe cases suggests that there is potential for safely managing more mild cases in outpatient settings.
