The Value of Follow-Up Liver Stiffness Changes Measured by Virtual Touch Quantification Elastography for Predicting Recurrence of Gastroesophageal Varices after Endoscopic Injection Sclerotherapy on Cirrhotic Patients

Table 4

Performance of ΔLS for evaluating recurrence of GEVs.

Cohorts	AUC	95% CI	Cut-off value	Sensitivity (%)	Specificity (%)	LR (+)	LR (-)
Training cohort	0.806	0.640-0.918	0.556	88.89	66.67	2.67	0.17
Validation cohort	0.741	0.568-0.872	0.389	83.33	55.56	1.88	0.30

ΔLS: liver stiffness differences; AUC: area under curve; GEVs: gastroesophageal varices; 95% CI: 95% confidence intervals; LR (+): positive diagnostic likelihood ratio; LR (-): negative diagnostic likelihood ratio.
