Sibling count and family employment status shape injury patterns and emergency department resource use in pediatric trauma.
Observational study in BMC emergency medicine, 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
backgroundPaediatric trauma presentations to emergency departments (EDs) are typically low in severity, yet they constitute a substantial component of ED workload. Although social determinants of health influence paediatric injury risk, the role of family structure in shaping injury patterns and healthcare utilisation remains insufficiently explored.
objectiveTo examine associations between sibling count, family characteristics, injury patterns, and ED resource utilisation in paediatric trauma.
methodsThis prospective single-centre observational study included children aged 0–15 years presenting with traumatic injuries between October 2025 and January 2026. Demographic variables, household characteristics (sibling count, parental employment status, caregiver availability), and trauma data were recorded prospectively. Associations between sibling count, injury patterns, and ED resource use were analysed using non-parametric tests and multivariable logistic regression adjusted for age and sex.
resultsAmong 408 patients (median age 8 years; 62.3% male), overall injury severity was low (median ISS 2) and not associated with sibling count. Higher sibling counts were independently associated with extremity fractures or dislocations (adjusted OR 1.32 per additional sibling, 95% CI 1.10–1.57), and children with ≥ 3 siblings had higher odds of extremity fractures (adjusted OR 2.76). Head injuries were more frequent among children with fewer siblings. Higher sibling counts were also associated with increased specialist consultation requirements.
conclusionsSibling count was associated with injury patterns and selected indicators of ED resource utilisation but not with overall trauma severity. Household context may therefore influence exposure patterns and care pathways in low-acuity paediatric trauma.
