Risk scores for predicting early recurrence in 2126 patients who underwent resection for hepatocellular carcinoma. a Distributions of the risk scores calculated from the model using least absolute shrinkage and selection operation regression for early recurrence among the entire patient cohort. b The optimum cutoff value for the risk score was determined using the maximally selected rank statistics (cutoff point = 0.649, standardized log-rank statistic = 14.05). c The discriminative power of the risk score model for recurrence-free survival; 1425 (67.0%) and 701 (33.0%) patients were identified as low-risk and high-risk for early recurrence with a 2-year recurrence-free survival rate of 75.2% (95% confidence interval [CI] 72.9%–77.6%) and 46.4% (95% CI 42.6%–50.4%), respectively. Patients in the high-risk group showed worse recurrence-free survival (hazard ratio = 2.970; 95% CI 2.561–3.446; P < 0.001). d The high-risk group also showed a higher monthly recurrence hazard rate within the first 2 years of resection than did the low-risk group
