fibrosis

Synthetic dataset generated to simulate data from a study that aimed to assess the predictive ability of a constructed score to determine the worsening in the fibrosis stage in individuals infected by the hepatitis C (HC) virus. When participants underwent a target revision, their fibrosis stage, certain polymorphisms, and other clinical variables were collected. Highest stages of fibrosis were considered a worsening in the disease. See References for more information about the study.

Provides estimations of the Receiver Operating Characteristic (ROC) curve and the Area Under the Curve (AUC) based on the two-stages mixed-subjects ROC curve estimator (Diaz-Coto et al. (2020) <doi:10.1515/ijb-2019-0097> and Diaz-Coto et al. (2020) <doi:10.1080/00949655.2020.1736071>).
