Hypothesis
The concordance between liver stiffness measurements (LSM) and FibroTest (FT) would be improved by excluding high-risk patients.
Conclusion
The study validated the use of concordance between non-invasive estimates of liver fibrosis to identify variability factors and precautions for use.
Supporting Evidence
- Applying manufacturers' recommendations increased the strength of concordance between LSM and FT.
- Older age and NAFLD were identified as factors associated with lower concordance.
- Biopsy confirmed the diagnostic value of LSM and FT for predicting advanced fibrosis.
Takeaway
Doctors can use new tests to check for liver damage without needing a painful biopsy, and this study shows how to make those tests more accurate.
Methodology
The study compared liver stiffness measurements and FibroTest results in patients, validating findings with liver biopsy.
Potential Biases
Potential operator effects and variability factors related to patient demographics and conditions could bias results.
Limitations
The study relied on retrospective liver biopsies rather than simultaneous biopsies, which could introduce variability.
