Table 2 Mean ELF scores for cases and controls in recruitment samples, subsequent samples and in the combined subsequent samples. Numbers of participants in each group are shown with corresponding mean ELF test score, for first sample (recruitment samples), subsequent sample 1 (second samples) and subsequent sample 2 (third samples)

From: The Enhanced Liver Fibrosis test is associated with liver-related outcomes in postmenopausal women with risk factors for liver disease
