Area of Science:

  • Hepatitis research
  • Machine learning in medicine
  • Virology

Background:

  • Hepatitis B (HBV) and Hepatitis C (HCV) are chronic diseases leading to severe liver conditions like cirrhosis and cancer.
  • Early diagnosis of viral hepatitis is crucial for effective management and reducing mortality.
  • Predictive models can aid in early detection and control of hepatitis outbreaks.

Purpose of the Study:

  • To compare the predictive performance of traditional and ensemble machine learning methods for HBV and HCV.
  • To identify significant variables associated with HBV and HCV infections.
  • To evaluate the accuracy of Random Forest, Bagging, AdaBoost, and Logistic Regression models.

Main Methods:

  • A case-control study conducted in Hamadan Province, Iran (2014-2019) with 534 participants (267 cases, 267 controls).
  • Ensemble learning methods (Bagging, Random Forest, AdaBoost) and Logistic Regression were employed for HBV and HCV prediction.
  • Model performance was assessed using accuracy metrics.

Main Results:

  • Random Forest demonstrated the highest accuracy (0.66 ± 0.03) for HBV prediction, identifying ALT as the most important variable.
  • For HCV prediction, Random Forest achieved an accuracy of 0.77 ± 0.03.
  • Variable importance for HCV prediction followed the order: AST, ALT, and age.

Conclusions:

  • Ensemble learning, particularly Random Forest, outperformed traditional methods in predicting HBV and HCV.
  • The study highlights the potential of machine learning for early hepatitis diagnosis.
  • Key biomarkers like ALT, AST, and age are significant predictors for HBV and HCV.
