Etiology and short-term outcome of pediatric coma at a tertiary hospital in Douala, Cameroon.
Article in BMC pediatrics, 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
backgroundPediatric coma is a critical emergency with high morbidity and mortality in sub-Saharan Africa, where limited data hinders effective management strategies. Understanding its epidemiology and prognostic factors is essential for improving outcomes.
methodsA cross-sectional study with retrospective (1st January 2017 to 30 November 2018) and prospective (1st December 2018 to 30th April 2019) phases was conducted at Gyneco-Obstetric and Pediatric Hospital of Douala, Cameroon. Children aged 1 month to 15 years with Glasgow Coma Scale (GCS) ≤ 14 were included. Data on demographics, clinical presentation, etiology, and outcomes were collected. Statistical analysis used SPSS version 20.0 and CSPro with Chi-square, Fisher's exact tests, and multivariable logistic regression.
resultsAmong 864 hospitalized children, 109 presented with coma (prevalence 12.6%), comprising 88 retrospective and 21 prospective cases. The male-to-female ratio was 1.4:1, with mean age 48.8 ± 47.5 months; 64.2% were under 5 years. Infectious causes predominated (62.4%, n = 68), with cerebral malaria accounting for 42.2% (46/109) and septicemia 15.6% (17/109). Other etiologies included metabolic/toxic causes (16.5%, 18/109), post-epileptic coma/status epilepticus (14.7%, 16/109), and traumatic brain injury (4.6%, 5/109); 12.8% (14/109) remained undiagnosed. Clinical features included fever (73.4%, 80/109) and seizures at admission (68.8%, 75/109). Overall mortality was 26.6% (29/109), with 30.9% (25/81) of survivors experiencing neurological sequelae, predominantly motor deficits (14.8%, 12/81). In multivariable analysis, significant mortality predictors included age under 2 years (adjusted OR 4.55, 95% CI: 1.23-16.82), female sex (adjusted OR 2.89, 95% CI: 1.23-6.79), direct home admission (adjusted OR 2.76, 95% CI: 1.02-7.47), and deeper coma stages (Stage III-IV: adjusted OR 6.92, 95% CI: 2.54-18.86).
conclusionPediatric coma at this tertiary center in Douala predominantly affects young children and stems primarily from infectious etiologies, particularly cerebral malaria. The high mortality (26.6%) and substantial neurological morbidity among survivors underscore urgent needs for strengthened malaria prevention programs, improved community awareness, enhanced referral systems, and increased diagnostic and intensive care capabilities. Early recognition and prompt management of preventable causes could significantly reduce mortality and morbidity from pediatric coma in Central Africa.
