Health outcomes and health-seeking behaviour following traumatic brain injury among older people: a prospective cohort study in Bangladesh.
Article in Frontiers in aging, 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
Background: Older adults are at high risk for traumatic brain injury (TBI), yet there is limited evidence on their vulnerability to mortality, morbidity, and associated risk factors in low-and-middle-income countries. This study assessed the burden, health outcomes, and health-seeking behavior of TBI in older adults at the largest teaching hospital in Bangladesh. Methods: The study analyzed data from individuals aged 60+ years who were part of a prospective observational cohort of TBI patients admitted to a teaching hospital in Dhaka, Bangladesh, from May to June 2017. Data were collected at admission and during discharge or a 30-day follow-up (whichever came earlier) using a pre-tested semi-structured questionnaire, including the Glasgow Coma Scale (GCS), Glasgow Outcome Scale (GOS), and EuroQol-5D-3L. Descriptive analyses assessed the burden, characteristics, and health-seeking behavior for TBI, while relative risks were calculated to evaluate the risk of mortality by socio-demographic characteristics and clinical status. Results: During the study period, 117 older TBI patients were admitted, with 78.6% being male. Road traffic injuries (RTI) accounted for 71.3% of cases, followed by falls (16%). Half of the patients did not receive treatment at the primary and secondary facilities they initially visited, and 16% experienced over 24 h' delay in treatment initiation. On admission, 25% presented with severe injury (GCS ≤8), and all had a history of loss of consciousness. The mortality rate was 5.2 per 1,000 person-days. Severe mobility issues and anxiety/depression were reported by 11% during follow-up. Bivariate analysis indicated higher mortality risk in patients with low socio-economic status, GCS ≤8, and over 1-h duration of both loss of consciousness and post-traumatic amnesia. Conclusion: RTI and falls are major causes of TBI, disproportionately affecting older adults of lower socio-economic status. Treatment accessibility gaps exist, and clinical status at admission is critical for predicting mortality. Findings can inform policies for preventive and rehabilitative strategies, including priority management protocols for older TBI patients in Bangladesh.
