Effect of corticosteroids on haemoglobinuria resolution among children with blackwater fever at Soroti regional referral hospital, Uganda: a retrospective cohort study.
Article in Malaria journal, 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
backgroundCorticosteroids are sometimes used in clinical practice in the treatment of blackwater fever (BWF), a complication of severe malaria, despite limited evidence of benefit. This study aimed to compare the time to haemoglobinuria resolution between children with BWF who received corticosteroids and those who did not, and determine if corticosteroid use significantly influences this outcome.
methodsThis was a retrospective cohort study carried out at Soroti Regional Referral Hospital in Soroti, Uganda, among children diagnosed with blackwater fever (BWF), between 1st January 2023 to 31st December 2024. Participants included in the study were 889. Time to haemoglobinuria resolution was determined using the Kaplan-Meier survival function and compared using log rank test. Predictors of time to haemoglobinuria resolution were determined using an extended cox proportional hazard model, with results expressed as adjusted hazard ratios (aHR) and 95% confidence intervals (CI).
resultsThe median time to haemoglobinuria resolution was 3 days in both the corticosteroid and non-corticosteroid groups. Corticosteroid use was not significantly associated with time to haemoglobinuria resolution (aHR: 0.90; 95% CI 0.75-1.07, p = 0.239). The predictors of time to haemoglobinuria resolution were: antibiotic use (aHR: 0.68; 95% CI 0.58-0.81, p < 0.001), blood transfusion (specifically for those who received transfusions twice [aHR: 0.78; 95% CI 0.62-0.97, p = 0.024], three times [aHR: 0.59; 95% CI 0.40-0.88, p = 0.010], and four times [aHR: 0.36; 95% CI 0.24-0.53, p < 0.001]), presence of jaundice (aHR: 1.49; 95% CI 1.14-1.94, p = 0.003), and administration of normal saline (aHR: 0.57, 95% CI 0.45-0.74, p < 0.001).
conclusionCorticosteroid use did not accelerate haemoglobinuria resolution in children with blackwater fever, supporting current WHO guidance against their use. These findings suggest limited benefit of corticosteroids in BWF management.
