Alpha-1 antitrypsin deficiency and Pi*Z allele as important co-factors in the development of liver fibrosis

Figure 1 Receiver operating characteristic curves illustrating the diagnostic ability of the patients’ age, age at diagnosis, and alpha-1 antitrypsin at diagnosis in predicting a nonalcoholic fatty liver disease fibrosis score value that does not exclude advanced fibrosis. A: The patients’ age; B: Age at diagnosis; C: Alpha-1 antitrypsin at diagnosis. AAT: Alpha-1 antitrypsin; AUC: Area under the curve.
