Preoperative and postoperative urinary NGAL levels in children with bladder exstrophy.
Article in Journal of nephrology, 2023. 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
backgroundUrinary NGAL (neutrophil gelatinase-associated lipocalin) levels have been shown to predict renal damage in various medical conditions. The present study was conducted to study the role of urinary NGAL levels in children with bladder exstrophy-epispadias complex post single-stage total reconstruction (SSTR) as markers of early renal function reduction.
methodsUrine samples were collected from children with bladder exstrophy before SSTR (Group A, n = 11), 5 years post SSTR (Group B, n = 40) and controls (Group C, n = 41) and stored at - 20 °C. NGAL levels were estimated using double antibody sandwich ELISA.
resultsMean NGAL levels in Groups A, B and C were 1.39, 34.24 and 2.58 ng/ml, respectively. Mean NGAL levels among Group B subjects with glomerular filtration rate (GFR) ≥ 80 ml/min/1.73 m
conclusionsIncreasing levels of urinary NGAL following bladder-exstrophy and epispadias complex repair suggest that NGAL detects the earliest signs of renal damage even before any deterioration is observed in DMSA and/or DTPA-GFR scans. Further studies with an adequate sample size and periodic measurement of NGAL need to be performed before any definitive conclusion can be drawn.
