Measuring and estimating the GFR in children: state of the art in 2025.
Review in Pediatric nephrology (Berlin, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Glomerular filtration rate (GFR) can be measured directly, or estimated from biomarkers like serum creatinine and cystatin C, or both. Measuring GFR in children is cumbersome, as it requires the intravenous injection of an exogenous filtration marker like iohexol, and several blood samples to determine the concentration-time decay curve. Serum creatinine (SCr) measurement is inexpensive and is part of the routine biochemical blood tests that are commonly requested in daily clinical practice. SCr-based estimated GFR is therefore still the most widely used test to obtain information on kidney function, although SCr varies with age and sex during childhood and GFR remains nearly constant over the 2-18-year age range. These issues are partially resolved by factoring SCr by height, or rescaling SCr by the median of healthy subjects, making interpretation of SCr and eGFR more straightforward. Cystatin C has become an interesting alternative kidney biomarker, and estimating GFR from cystatin C has therefore become more important. The aim of this review is to show recent advances in measuring and estimating GFR in children.
