In the article entitled “EASL-EASD-EASO Clinical Practice Guidelines on the Management of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)” [Obes Facts. 2024;17(4):374–444; DOI: 10.1159/000539371], by the European Association for the Study of the Liver (EASL), European Association for the Study of Diabetes (EASD) and European Association for the Study of Obesity (EASO), the formulation listed in the original text was correct but was based on a previous generation of lab analyzers. With the introduction of a new generation of lab analyzers for this test, the formula was slightly modified to obtain the ELF (enhanced liver fibrosis) test. Since most laboratories worldwide use this new formulation and the referenced meta-analysis was primarily based on studies using this new formulation, the authors request that the following paragraph on page 13 be updated to provide the most up-to-date formulation to the readers:

“The ELF (enhanced liver fibrosis) test produces a single score based on quantitative measurements of three serum markers of extracellular collagen metabolism. ELF = 2.494 + 0.846 In(hyaluronic acid) + 0.735 In(amino-terminal propeptide of type III procollagen [PRO-C3]) + 0.391 In(tissue inhibitor of metalloproteinases 1) according to the ADVIA Centaur CP System [147].

In a meta-analysis of 63 studies, ELF showed a relatively high performance in detecting significant fibrosis, advanced fibrosis or cirrhosis (AUROCs 0.811, 0.812 and 0.810, respectively) [148].”

should be updated to:

“The ELFTM (enhanced liver fibrosis) test produces a single score based on quantitative measurements of three serum markers of extracellular collagen metabolism [147]. ELF = 2.278 + 0.851 × In(hyaluronic acid [HA]) + 0.751 × In(amino-terminal propeptide of type III procollagen [PIIINP]) + 0.394 × In(tissue inhibitor of metalloproteinase 1 [TIMP-1]) as measured on the ADVIA Centaur XP/XPT system, Atellica IM Analyzer and Atellica CI Analyzer.

In a meta-analysis of 63 studies, ELF showed a relatively high performance in detecting significant fibrosis, advanced fibrosis or cirrhosis (AUROCs 0.811, 0.812 and 0.810, respectively) [148].”
