“… 10 Currently, accumulating evidence has shown that inflammation‐based scores, such as systemic immune‐inflammation index (SII), platelet‐to‐lymphocyte ratio (PLR), neutrophil‐to‐lymphocyte ratio (NLR), lymphocyte‐to‐monocyte ratio (LMR), prognostic nutritional index (PNI), aspartate aminotransferase/platelet count ratio index (APRI), aspartate aminotransferase (AST) to neutrophil ratio index (ANRI), and AST to lymphocyte ratio index (ALRI) could be used as the prognostic markers for cholangiocarcinoma. 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 Gamma‐glutamyl transpeptidase (GGT) to albumin ratio (GAR) was a newly identified inflammation‐based score. Initially, GAR was pointed out to be useful for stratification of patients with chronic hepatitis B.…”
