Prevalence and clinical impact of Vitamin A Deficiency (VAD) in critically ill children with sepsis.
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
backgroundData on vitamin A deficiency (VAD) among critically ill pediatric patients with sepsis and its impact remain limited. This study aimed to determine the prevalence of VAD in septic children and evaluate its association with clinical outcomes.
methodsThis prospective cohort included 180 children with sepsis admitted to the Pediatric Intensive Care Unit (PICU) of Benha University Hospital, and 40 healthy controls. Using ELISA, serum vitamin A (VA) levels were measured upon admission. Clinical parameters, including the Pediatric Risk of Mortality (PRISM) scores, sepsis progression, ventilation duration, PICU stay, and mortality were assessed. Multivariate regression evaluated the relationship between VAD and sepsis severity.
resultsVAD was significantly more prevalent among septic patients than controls (61.7% vs. 20%, P < 0.001). ROC analysis identified serum VA ≤ 21.4 µg/dl as a significant predictor of sepsis (AUC = 0.699, P < 0.001). While VAD was more frequent in non-survivors (71.4%), the association with mortality was not statistically significant. VAD was linked to higher PRISM scores, longer PICU stays, and greater sepsis severity.
conclusionOur cohort found that VAD is more prevalent in pediatric sepsis patients compared to controls and correlated with higher PRISM scores, sepsis severity and prolonged stays in PICUs. Nevertheless, VAD did not demonstrate a statistically significant association with 28-days mortality. These findings highlight the necessity for additional large-scale research to determine if routine screening of VAD and potential supplementation could improve outcomes in these patients.
