Table 6 Cutoff values of SWE (kPa) for AIT and Sensitivity, Specificity, PPV, NPV and diagnostic accuracy of these cutoff value

From: Shear wave elastography as a quantitative method for thyroid gland elasticity assessment in pediatrics patients with autoimmune-related thyroid disease, diagnostic utility and laboratory correlation

Cutoff value (kPa) Sensitivity (%) Specificity (%) PPV (%) NPV (%) Diagnostic accuracy (%)
13.217 96.9 100 100 96.9 98
  1. PPV positive predictive value; NPV negative predictive value; kPa kilopascals; SWE shear wave elasticity; AIT autoimmune thyroiditis
