Amyloidosis secondary to familial Mediterranean fever: machine learning–based prediction models

Rheumatology (Oxford)Published Retrospective cohort study

Authors' conclusion

Amyloidosis, the most severe FMF complication, is driven by key clinical and genetic factors, with ensemble machine-learning models outperforming conventional regression for early risk prediction.
