Microalbuminuria in children with cyanotic congenital heart disease in Enugu, Nigeria; a comparative study.
Article in BMC nephrology, 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
backgroundChildren with congenital heart diseases are at increased risk of developing chronic kidney disease (CKD) later in life, and children with cyanotic congenital heart disease (CCHD) are at greater risk.
objectivesThis study aimed to determine the prevalence of microalbuminuria and the associations between microalbuminuria and age, oxygen saturation and haematocrit in children with cyanotic congenital heart disease.
methodsThis was a comparative, cross-sectional analytical study carried out over a period of six months. Thirty-six children with CCHD and thirty-six apparently healthy children were enrolled consecutively. Haematocrit levels, oxygen saturation, serum and urine creatinine levels and urine albumin levels were determined for eligible participants. A urine albumin/creatinine ratio in the range of 30-300 mg/g was classified as positive for microalbuminuria. Parametric and nonparametric tests were performed to determine the associations between the dependent and independent variables.
resultsThe prevalence rates of microalbuminuria were 38.9% (95% CI: 20.1, 56.5) and 5.6% (95% CI: 0.67, 18.7) in children with CCHD and in apparently healthy children, respectively. More children with CCHD than apparently healthy children had microalbuminuria. χ
conclusionThis study demonstrated that children with CCHD are more likely to have microalbuminuria than are children who appear to be in good health and that microalbuminuria in this group of children is related to higher haematocrit levels. Early screening of this group of children is recommended to reduce the risk of progressive kidney disease. CLINICAL TRIAL NUMBER: Not applicable.
