2D Shear wave elastography for evaluation of renal cortex and medulla: stiffness values in healthy children.
Article in Abdominal radiology (New York), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeTo evaluate renal cortical and medullary stiffness using 2D Shear-wave elastography (SWE) in healthy children.
methodsIn this IRB approved prospective study, we measured the stiffness of cortex and medulla of children (4 months-17 years) at the upper pole, mid pole, and lower pole in bilateral kidneys.
resultsThe median (IQR) values of renal cortex in <1 year age group was 8.7 (5.7-11.7) kPa for right and 8.7 (4.2-14.1) kPa for the left side. For 1-5 years age group, it was 7.3 (5.3-10) kPa for the right and 8.9 (6-12.3) kPa for the left side. For >5 years, it was 7.4 (5.3-11.2) kPa for the right and 9.6 (6.2-12.7) kPa for the left side. The median (IQR) values of renal medulla in <1 year age group was 7.1 (5.1-12.5) kPa for right and 6.8 (4-10.6) kPa for the left side. For 1-5 years age group, it was 7.2 (4.9-9.7) kPa for the right and 6.9 (5.6-9.9) kPa for the left side. For >5 years, it was 6.8 (5.1-9.6) kPa for the right and 7 (5-10.2) kPa for the left side. The differences in the elasticity values amongst these groups were statistically insignificant (p>0.05). There was a significant correlation between SWE values of cortex and medulla of right kidney (ρ=0.64) and of left kidney (ρ=0.61), respectively.
conclusionSWE values of renal cortical and medullary stiffness in healthy children do not correlate with age. There is a significant correlation between SWE values of cortex and medulla of the kidneys in healthy children.
