Risk factors associated with disease severity among children hospitalised with community-acquired pneumonia in Angola.
Observational study in Journal of global health, 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
Background: Community-acquired pneumonia (CAP) is a major cause of paediatric mortality worldwide, disproportionately affecting children in low- and middle-income countries. Yet, to date, no studies have examined the risk factors for severe CAP in Angolan children. We aimed to identify these risk factors to improve CAP-associated morbidity and mortality. Methods: We conducted a prospective, observational study enrolling a convenience sample of children aged two months to 13 years hospitalised with CAP in the Hospital Pediátrico David Bernardino in Luanda, Angola. We included healthy children and those with asthma, human immunodeficiency virus, or sickle cell disease. We used multivariable logistic regression to assess risk factors associated with mortality as the primary outcome and prolonged hospitalisation as the secondary outcome. Results: From September 2019 to May 2021, we enrolled 372 patients hospitalised with CAP, confirmed by chest x-ray. Multivariable analysis identified age <1 year (adjusted odds ratio (aOR) = 7.51; 95% confidence interval (CI) = 1.72-34.12), seizures (aOR = 10.62; 95% CI = 1.17-80.71), and C-reactive protein ≥150 mg/L (aOR = 27.77; 95% CI = 4.48-575.26) as risk factors for mortality, while cough prior to hospitalisation was a protective factor (aOR = 0.05; 95% CI = 0.01-0.2). Cooking at home with coal or wood (aOR = 2.05; 95% CI = 1.13-3.80), malnutrition (aOR = 2.15; 95% CI = 1.17-4.01), inability to drink on admission (aOR = 2.43; 95% CI = 1.22-5.00), diminished breath sounds on auscultation (aOR = 2.67; 95% CI = 1.49-4.82), and pleural effusion on chest x-ray (aOR = 3.99; 95% CI = 2.23-7.27) were risk factors for prolonged hospitalisation (>7 days). Conclusions: We identified various demographic, environmental, clinical, laboratory, and radiologic findings as key risk factors for severe CAP in Angolan children.
