Noninvasive prediction of esophagogastric varices in hepatitis B: An extreme gradient boosting model based on ultrasound and serology

Figure 2 Esophagogastric varices of varying severity and the corresponding spleen stiffness measurements. A: A 50-year-old male patient with mild esophagogastric varices (EGVs) as determined by endoscopy, with a median spleen stiffness value of 11.6 kPa; B: A 33-year-old male patient with moderate EGVs as determined by endoscopy, with a median spleen stiffness value of 19.5 kPa; C: A 59-year-old female patient with severe EGVs as determined by endoscopy, with a median spleen stiffness value of 25.4 kPa.
