Strong non-invasive tests (NITs) are needed to predict decompensation in patients with compensated advanced chronic liver disease (cACLD) and improve personalized patient care. We conducted a comprehensive review of the studies evaluating the effectiveness of NITs in predicting decompensation or liver-related death in patients with cACLD. A literature search was conducted in the PubMed database up to August 2025. Prospective or retrospective studies that included patients with cACLD and evaluated NITs for predicting decompensation or death or liver transplantation were included. Studies evaluating elastography and blood-based tests were analysed separately. The majority of studies assessed liver stiffness measurement (LSM), primarily using transient elastography (TE-LSM). There is a strong association between higher LSM values and an increased risk of decompensation, allowing classification of patients at low risk of decompensation from those with a higher risk. However, none of the studies reported data calibration, thereby limiting the ability to accurately predict the individual risk of decompensation. Higher FIB-4, ELF, and MELD values have been associated with an increased occurrence of decompensation. However, their performance was modest, with an area under the curve (AUC) below 0.75. Innovative approaches to improving the non-invasive prediction of decompensation may include levels of extracellular vesicles, genetic polymorphisms, or imaging-derived variables. Furthermore, since decompensation is the result of numerous interacting factors, artificial intelligence has the potential to improve the clinical relevance of predictive models by incorporating and processing a high-dimensional set of variables that reflect the underlying pathophysiological complexity.
