Apart from variations in the severity of the endpoints (from the liver failure (Fig. 5a) and the radiation-induced liver injury (Fig. 5b) to the potentially slightly less severe toxicities such as changes in albumin-bilirubin (ALBI) score, Child–Pugh (CP) score, or enzymatic changes (Fig. 5c-f), the models also use different parameters as reported in Table 2. Here, ALB is linked to Hepatic failure.
