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
backgroundSudanese children with End-Stage Kidney Disease (ESKD) often show limited improvement in hemoglobin levels despite treatment with recombinant human erythropoietin (rHuEPO). This study aims to assess the response to rHuEPO therapy by analyzing β-globin mRNA expression and reticulocyte parameters. Additionally, it classifies anemia among Sudanese pediatric patients based on iron status, considering age and gender as biological markers for evaluating treatment response.
methodsA prospective observational cohort study was conducted from January 2019 to February 2020 in Khartoum, Sudan, involving 45 anemic children aged 2 to 15 years diagnosed with ESKD. The treatment protocol included rHuEPO injections and maintenance hemodialysis. Laboratory assessments consisted of complete blood count (CBC), absolute reticulocyte count, ferritin, and transferrin measurements. β-globin mRNA expression was quantified using reverse transcription polymerase chain reaction (RT-PCR), and reticulocyte parameters, including Reticulocyte Hemoglobin Content (CHr), percentage of hypochromic reticulocytes (HYPO%), and Immature Reticulocyte Fraction (IRF), were measured via flow cytometry.
resultsSignificant variations in hemoglobin levels were observed across different age groups (p = 0.011). Gender analysis revealed a significant association with IRF, showing a lower IRF in male patients (p = 0.017). However, there were no significant differences in hemoglobin levels between genders (p = 0.999). β-globin mRNA expression showed considerable variability, with a strong positive correlation with hemoglobin levels (r = 0.875, p < 0.0001).
conclusionAge and gender significantly influence treatment responses in children with ESKD, highlighting the need to consider growth physiology in anemia management. This study underscores the variability in β-globin mRNA expression and its association with Flow Cytometry parameters, demonstrating their effectiveness in evaluating iron status and guiding rHuEPO dosage.
