Exploratory analyses of NASH histology using CRN scores derived from a multi-stain machine learning method

November 07, 2022

Study Background

Non-alcoholic steatohepatitis (NASH) biopsies are evaluated using both hematoxylin and eosin (H&E) and Masson’s Trichrome (TC) stains, but this process is subject to high variability. Machine learning (ML) methods train distinct H&E and TC models to assess respective histologic components and improve reproducibility over manual scoring. We previously developed a novel ML-based model to extract and combine complementary histologic information from H&E and TC stains to predict NASH Clinical Research Network (CRN) grades/stages, improving accuracy over single-stain ML approaches. Here, we performed exploratory analyses of learned model-derived features. Abel et al.
