Contribution of vitamin B 6 deficiency to anemia in children on regular hemodialysis.
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
backgroundAnemia is prevalent among pediatric patients diagnosed with end-stage kidney disease (ESKD). In addition, erythropoiesis-stimulating agents (ESA) and iron supplementation are considered the cornerstones in the management of anemia. However, a significant proportion of patients remain anemic. Vitamin B6 plays a vital role in the biosynthesis of heme and may be deficient in children with chronic kidney disease (CKD), particularly those on regular hemodialysis (HD). We aimed to evaluate serum vitamin B6 concentration in those children and determine its correlation with anemia indices.
methodsThe current cross-sectional study included 39 children on regular HD and 43 healthy controls. Clinical data were collected, including anthropometric measurements, blood pressure, iron, and erythropoietin therapy. Laboratory investigations included hemoglobin (Hb) indices, iron profile, and vitamin B6 level.
resultsThe median Hb level in our cohort was 10.5 g/dL, and nine patients had Hb levels at or above the target Hb of 11 g/dl. They had a median Serum Vitamin B6 concentration of 28.2 ng/ml (IQR = 22.8-52.9) compared to a median of 27.5 ng/ml(IQR = 20-34) in controls, with no substantial differences between both groups. There was no statistically significant correlation between vitamin B6 and Hb levels or erythropoietin dose.
conclusionIt is evident that the majority of our patients did not meet the desired threshold for anemia control. However, it is noteworthy that the average hemoglobin (Hb) level approached the intended target. The incidence of Vitamin B6 deficiency was not found to be statistically significant within our study population. Therefore, we could not establish a correlation between vitamin B6 deficiency and anemia in children on HD.
