Incidence and predictors of mortality among traumatic brain injury patients in Ethiopia: a systematic review and meta-analysis.
Article in Journal of trauma and injury, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTraumatic brain injury (TBI) represents a significant public health concern due to its high incidence, substantial prevalence of chronic neuropsychiatric sequelae, disabilities, and economic burdens. Although several primary studies have examined mortality rates among individuals with TBI in Ethiopia, no systematic reviews and meta-analyses have yet synthesized these findings to provide a comprehensive nationwide estimate.
methodsA systematic search for Ethiopian TBI mortality studies was conducted using PubMed, MEDLINE, Hinari, ScienceDirect, Ovid, the Web of Science, the Directory of Open Access Journals, and the African Journals Online. Following the PRISMA guidelines, we screened eligible studies, assessed quality with the Joanna Briggs Institute tool, and analyzed data in Stata ver. 18. A random-effects model estimated TBI mortality and the pooled odds ratios (PORs) of predictors. Heterogeneity (I2) was assessed, and subgroup analyses, meta-regression, forest plots, and funnel plots with Egger and Begg tests addressed variability and publication bias.
resultsOf 100 records, 23 studies (n=7,866) met inclusion. The pooled incidence of mortality from TBI in Ethiopia was 15.69% (95% confidence interval [CI], 12.41-18.96). Regional incidence varied from 3.15% (95% CI, 1.23-5.08) in the Sidama Region to 39.42% (95% CI, 33.25-45.59) in the Amhara Region. Identified predictors of mortality included aspiration pneumonia (POR, 10.41; 95% CI, 3.25-33.40), penetrating injury (POR, 1.76; 95% CI, 1.07-2.90), road traffic accident injuries (POR, 1.71; 95% CI, 1.11-2.64), severe Glasgow Coma Scale (GCS) scores (POR, 18.94; 95% CI, 7.37-48.7), moderate GCS scores (POR, 2.95; 95% CI, 1.60-5.44), bilateral pupillary reaction (POR, 24.56; 95% CI, 7.72-78.19), unilateral pupillary reaction (POR, 7.75; 95% CI, 4.45-13.48), hypoxia (POR, 8.22; 95% CI, 2.42-27.98), concomitant injuries (POR, 2.15; 95% CI, 1.05-4.38), complications (POR, 4.76; 95% CI, 2.49-9.09), surgical management (POR, 0.58; 95% CI, 0.36-0.94), and mechanical ventilation (POR, 4.45; 95% CI, 2.00-9.88).
conclusionsThe high TBI mortality in Ethiopia underscores the urgent need to expand advanced trauma care centers, deploy trained personnel beyond urban areas, and strengthen road safety policies to achieve Sustainable Development Goal targets by 2030.
