Context-specific predictors of mortality and the performance of paediatric sepsis scores in Tanzanian children: a secondary analysis of a prospective cohort study.
Article in BMJ paediatrics open, 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
introductionSepsis is a significant cause of global child mortality, disproportionately affecting resource-limited settings (RLS). Although clinical scores have been proposed in RLS, few have been externally validated. This study aimed to identify risk factors for mortality among Tanzanian children with sepsis and test three paediatric clinical scores in an RLS.
methodsWe conducted a secondary analysis of a prospective cohort study of 755 children (28 days to 14 years) with sepsis in the Emergency Department at Muhimbili National Hospital, Tanzania (July 2022-November 2024). Demographic, clinical and outcome data were collected. We performed multivariable logistic regression to identify independent predictors of in-hospital mortality. We then tested three clinical scores, Lambaréné Organ Dysfunction Score (LODS), Blantyre quick Sequential Organ Failure Assessment (BqSOFA) and Phoenix Sepsis Score (PSS), using sensitivity, specificity and area under the receiver operating characteristic curve (AUC).
resultsIn-hospital mortality was 20% (n=148); independent predictors included age, malnutrition, HIV status, referral status and delayed presentation (p<0.001). All three scores demonstrated strong discrimination for mortality (LODS AUC 0.79, 95% CI 0.75 to 0.83; BqSOFA AUC 0.75, 95% CI 0.71 to 0.79; PSS AUC 0.75, 95% CI 0.70 to 0.79) and differences between scores were not statistically significant (p=0.066). LODS showed high sensitivity (93%) and negative predictive value (96%). BqSOFA and PSS demonstrated high specificity (93% and 91%) and positive predictive values (51% and 56%), but low sensitivity (28% and 44%).
conclusionsMultiple clinical and sociodemographic factors were independently associated with mortality in children with sepsis. LODS demonstrated high sensitivity, while BqSOFA and PSS demonstrated high specificity; the scores' discriminative ability for mortality was not statistically significant. The identification of simple risk factors and moderately performing clinical scores provides a valuable opportunity to develop context-specific risk stratification tools for paediatric sepsis in RLS.
