The Combination of Shear Wave Elastography and Platelet Counts Can Effectively Predict High-Risk Varices in Patients with Hepatitis B-Related Cirrhosis

Figure 2

Distribution of liver stiffness was subdivided based on the absence of EVs, presence of LRVs or HRVs in all patients (a). The red and blue horizontal lines represent cut-offs of 2D-SWE for varices of all sizes and high-risk varices, respectively. Calibration plot of 2D-SWE (bootstrap resampling ) for high-risk varices and varices of all sizes in all patients (b) and (c). Calibration slopes graph the agreement between predicted probability on the -axis and observed proportion on the -axis. The black dashed line represents perfect calibration, with 100% agreement. Red line represents the performance of 2D-SWE, and blue dashed line represents 95% confidence intervals of observed probabilities. Abbreviations: EVs: esophageal varices; LRVs: low-risk varices; HRVs: high-risk varices; 2D-SWE: two-dimensional shear wave elastography; kPa: kilopascals.
