A machine learning approach was developed and validated to improve detection of NASH using NAS-based definitions and to identify individuals with at-risk NASH. The study evaluates model performance in development and validation settings, aiming to enhance diagnostic reliability compared with existing limitations.","Downloaded from [http://journals.lww.com/hep by BhDMf5ePHKav1zEoum1tQfN4a](http://journals.lww.com/hep by BhDMf5ePHKav1zEoum1tQfN4a)+kJLhEZgbsIHo4XMi0hCywCX1AWn YQp/ I l Qr HD3i 3 D0OdRyi 7TvS Fl4Cf3VC 1y0abggQZXdtwnfKZBYtws= on 07/28/2023  \nDOI: 10.1097/HEP.0000000000000364  \nO R IG INAL ART ICL E  \nMachine learning algorithm improves the detection of NASH (NAS-based) and at-risk NASH: A development and validation study  \nJenny Lee1  | Max Westphal2  | Yasaman Vali 1  | Jerome Boursier3  | Salvatorre Petta4  | Rachel Ostroff5  | Leigh Alexander5  | Yu Chen6 | Celine Fournier7  | Andreas Geier8  | Sven Francque9  |  \nKristy Wonders10  | Dina Tiniakos10, 11  | Pierre Bedossa10  |  \nMike Allison 12 | Georgios Papatheodoridis13  | Helena Cortez-Pinto14  | Raluca Pais 15  | Jean-Francois Dufour16  | Diana Julie Leeming 17  | Stephen Harrison 18  | Jeremy Cobbold 18 | Adriaan G.
