Core Tip

Core Tip: In this study, we constructed two liver fibrosis index (LFI)-based nomograms for predicting the risk and severity of esophageal varices (EV) in patients with chronic hepatitis B related cirrhosis, through incorporating the clinical and ultrasonic variables screened out by univariate and multivariate logistic regression analyses. The nomograms were well-calibrated and had a good discriminative ability that was validated by receiver operating characteristic curve, concordance index, and decision curve analyses. Both nomograms were more efficient than LFI, splenic portal index, ratio of platelet count to spleen diameter, King’s score, and Lok index in the training and validation cohorts, and can be clinically used for diagnosing EV and making clinical interventions.
