The liver fibrosis‐8 index is a predictor for all‐cause mortality in cardiovascular disease patients: A cohort study

A positive and linear correlation was observed between the FIB-8 index and all-cause mortality among CVD adult participants in NHANES from 1999 to 2018. Our findings indicated that the FIB-8 index could serve as an excellent indicator for assessing all-cause mortality within the CVD population. The lower the FIB-8 index, the lower the all-cause mortality among CVD participants.
