Table 1 Primary outcome analysis
From: Ultrasound real-time elastography can predict malignancy in BI-RADS®-US 3 lesions
Effect of sonoelastography on the probability of disease | ||
|---|---|---|
TES 1–3 or BGR-sign (test negative, benign elastogram, low-risk group) | TES 4–5 (test positive, suspicious elastogram, high-risk group) | |
pretest POD | 4.5% a, b (2.1-9.0) | |
posttest POD | 2.2% b, c (0.6-6.7) | 13.2% a, c (5.0-28.9) |
Likelihood ratio | 0.5 (0.2-1.1) | 3.2 (1.7-5.9) |
