GSTM1 and Cirrhosis: When the predictive properties of haematological parameters and mortality scores were evaluated, we found that PCT, RDW, Hb/RDW ratio, AAR, MELD score, and PELD values, which are the best cut-off values to predict cirrhosis, had high sensitivity and specificity in predicting cirrhosis (p < 0.001) (Table 4).
