Erythrocyte deformability and microhematuria in children and adolescents.
Article in Pediatric nephrology (Berlin, Germany), 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The aim of this study was to investigate whether erythrocyte deformability is higher in otherwise healthy children and adolescents with asymptomatic isolated glomerular microhematuria and no clinical or laboratory signs indicating renal disorder. Erythrocyte deformability in 33 children and adolescents with unexplained asymptomatic isolated glomerular microhematuria (study group) was compared with erythrocyte deformability in 133 individuals without urinary tract disease and without microhematuria (control group), 26 patients with microhematuria and IgA nephropathy (IgA nephropathy group), and 31 children and adolescents with benign familial hematuria (benign familial hematuria group). The erythrocyte and buffer filtration time was measured, the erythrocyte-to-buffer filtration time ratio calculated, and, on the basis thereof, erythrocyte deformability was estimated as an inverse proportion of the erythrocyte-to-buffer filtration time ratio in all subjects. The erythrocyte-to-buffer filtration time ratio increased with age in all groups (P<0.001). In the study group, the mean erythrocyte-to-buffer filtration time ratio, corrected for age of subjects, was significantly lower than in the control (P=0.042), IgA nephropathy (P=0.004), and benign familial hematuria groups (P= 0.048). Erythrocytes with higher deformability probably pass more easily through the glomerular basement membrane that is assumed to be normal, in which case the mechanism of asymptomatic isolated glomerular microhematuria could be explained by higher erythrocyte deformability.
