[2025-10-02T00:55:12.242253] [PI reasoning] **Explaining Child-Pugh Score Categories**

I need to clarify that the Child-Pugh score categories are A (<7), B (7-9), and C (10-15), with an ordinal scale reflecting severity but not equal intervals. This classification is distinct from nominal or quantitative types. The correct answer is B, as the categories follow an ordered sequence. While I don’t need an extensive database search for a simple question, I still want to include a citation on the Child–Pugh classification. A quick search for related information will help me find a suitable article.
