[Retracted] Recurrence of Early Hepatocellular Carcinoma after Surgery May Be Related to Intestinal Oxidative Stress and the Development of a Predictive Model

Figure 4

Decision curves for obtaining RFS using the established model and staging system in the training and testing cohorts. The -axis measures the net benefit, which is calculated by adding together the benefit (true positive results) and subtracting the harm (false positive results), weighting the latter by a factor that compares the relative harm of undetected tumors to the harm of unnecessary treatment. The imaging combined with the gut microbiome model provided the best net benefit compared to the separate models and staging systems. Otu, operational taxonomic unit; Ra, radiomics; OR, operational taxonomic unit combines radiomics; BCLC, Barcelona clinic liver cancer; CNLC, Chinese liver cancer staging.
