Integrating morphology, vascularity, and elasticity: diagnostic role of multiparametric quantitative ultrasound in breast lesions.
Article in Journal of ultrasound, 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
objectivesTo determine the incremental diagnostic value of multiparametric quantitative ultrasound-integrating B-mode, Color Doppler, Strain, and Shear Wave Elastography (SWE)-in differentiating benign and malignant breast lesions, using histopathology/FNAC as the gold standard.
methodsSeventy patients with 87 breast lesions underwent comprehensive ultrasound by a resident and a consultant radiologist (> 20 years' experience) with consensus reporting. Each lesion was evaluated using B-mode (BI-RADS), Color Doppler (vascularity, resistive and pulsatility indices), Strain elastography (strain ratio), and SWE (stiffness in kPa). Pathological correlation was available for all lesions. Diagnostic performance of individual and combined parameters was assessed using sensitivity, specificity, PPV, NPV, accuracy, and ROC analysis. Multivariate logistic regression evaluated incremental value of multiparametric combinations.
resultsB-mode had the highest sensitivity (88.37%) and accuracy (82.76%), Color Doppler the highest specificity (95.45%) but low sensitivity (55.81%), while Strain and SWE showed balanced performance, with SWE achieving the highest accuracy (85.06%) and AUC (0.85). Adding Color Doppler or Strain to B-mode provided no additional benefit. Incorporating SWE improved specificity (88.64%) and accuracy (85.06%). B-mode + Strain + Color Doppler achieved 83.91% accuracy, whereas B-mode + SWE + Color Doppler provided the highest overall performance (sensitivity 86.05%, specificity 86.36%, accuracy 86.21%, AUC 0.86). The four-parameter model (B-mode + Color Doppler + Strain + SWE) showed 83.72% sensitivity, 86.36% specificity, AUC 0.85, and 85.06% accuracy, performing comparably but marginally inferior to the best triple combination (B-mode + Color Doppler + SWE), likely due to redundancy and threshold effects, indicating that adding Strain did not improve performance.
conclusionMultiparametric ultrasound enhances lesion differentiation. B-mode ensures sensitivity, Color Doppler confirms benign vascular patterns, and SWE provides quantitative stiffness assessment. Combining morphology, vascularity, and stiffness-particularly B-mode + SWE + Color Doppler-yields the highest diagnostic accuracy.
