1 · What the graph read from it

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.

2 · The registry

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

backgroundSingle measurements of serum cystatin C (cysC) concentration have generally been used to determine glomerular filtration rate (GFR) in adults. Since GFR varies to some extent among children, we attempted to determine reference serum cysC concentrations for Japanese children.

methodsSerum cysC concentrations were determined by a latex particle-enhanced turbidimetric immunoassay in children who did not present with kidney disease or infectious disease, and the relationship between age and serum cysC level was assessed.

resultsWe found that reference serum cysC levels gradually decreased during the first year after birth, thereafter becoming constant. Mean serum cysC concentration in children aged 1 year (0.76 ± 0.10 mg/L) was slightly higher than in children aged ≥2 years (0.70 ± 0.09 mg/L).

conclusionOur reference values will be applicable for screening renal function in Japanese children.
