Extended Data Fig. 4. Mapping of continuous scores.

Continuous MAS (steatosis, ballooning and lobular inflammation) and CRN fibrosis scores were produced by mapping GNN-derived ordinal grades/stages to bins, such that ordinal scores are spread over a continuous range (unit distance of 1). This continuous scoring system allows a more granular measurement of histological changes occurring at the subordinal level, while maintaining fidelity to the accepted ordinal scoring system.
