Risk factors for intracranial injuries in older adults with minor head trauma: how important is cutaneous lesion localization?
Article in BMC geriatrics, 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
backgroundOlder adults are susceptible to head trauma due to age-related changes. Even minor head trauma can lead to serious consequences. Our study aims to determine the impact of trauma location and characteristics on intracranial hemorrhage (ICH) in older adults.
methodsThis is a retrospective study conducted on patients aged 65 years and older with minor head trauma or suspected head trauma who presented to the emergency department (ED) of a tertiary university hospital and underwent a brain computed tomography (CT) scan during the 5-year period between 2019 and 2023. Cutaneous lesions were defined as laceration, hematoma, swelling, erythema, and ecchymosis. A binary logistic regression analyzed factors affecting ICH, such as age, gender, glasgow coma scale (GCS), anticoagulant use, head lesion location, witnessed trauma, trauma location, alcohol use, smoking, nausea-vomiting, amnesia, and neurological deficits.
resultsA total of 1191 eligible patients were analyzed. Brain CT revealed no acute pathology in 93% (n = 1108), while ICH was detected in 4.8% (n = 57). 77.2% (n = 44) of ICH patients and 89.5% (n = 23) of isolated skull fracture patients had head lesions. The rate of head cutaneous lesions was significantly higher in patients with ICH or isolated skull fractures (p < 0.001). The risk of ICH was 31 times higher in those presenting with low GCS (95% CI 12.944–74.702, p < 0.001). Individuals with frontal, parietal, occipital, temporal, or multiple lesions face significantly higher risks of ICH than those without lesions (8, 26, 18, 22, or 44 times, respectively). Additionally, patients with neurological deficits are nine times more likely to experience ICH than those without (p < 0.001).
conclusionsBrain CT is an established practice in the ED for diagnosing older adults who present with minor or suspected head trauma. In addition to previously studied findings such as neurological deficit and decreased GCS, cutaneous lesion localization in the skull also increases the risk of ICH according to its region. More comprehensive and multicenter studies are needed to include this determinant in scoring systems.
