Shear wave elastography and ultrasonic multi-parameter score for the identification of moderate-to-severe chronic kidney disease.
Article in BMC medical imaging, 2026. 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
objectiveThis study aimed to investigate the value of shear wave elastography (SWE) and an ultrasonic multi-parameter score in identifying chronic kidney disease (CKD) stage ≥ III (moderate-to-severe CKD) in patients with known CKD.
methodsA single-centre cross-sectional study was conducted, enrolling 152 patients with CKD (staged I-V according to estimated glomerular filtration rate). Conventional ultrasound parameters (renal length, parenchymal thickness, echogenicity) and SWE measurements (Young's modulus [YM] in kPa) of the renal cortex and medulla were obtained. The ultrasonic multi-parameter score was calculated using a standardised rubric. Receiver operating characteristic curve analysis was performed to evaluate the diagnostic performance of SWE cortical YM and the multi-parameter score for identifying CKD stage ≥ III.
resultsThe study included 23 patients with stage I CKD, 45 with stage II, 44 with stage III, 15 with stage IV and 25 with stage V. Shear wave elastography cortical YM (area under the curve [AUC]: 0.894) and the multi-parameter score (AUC: 0.870) showed promising discrimination for stage ≥ III CKD. Cortical YM demonstrated a specificity of 0.912 and a sensitivity of 0.671.
conclusionShear wave elastography cortical YM has high specificity, supporting its potential role in the rule-in of moderate-to-severe CKD. The ultrasonic multi-parameter score also shows clinical value for severity stratification. However, the relatively low sensitivity limits its utility for rule-out purposes. CLINICAL TRIAL NUMBER: Not applicable.
