Prognostic value of serum alpha-fetoprotein kinetics in liver failure on artificial liver support

Figure 2 Kaplan-Meier estimates of 3-month survival and areas under the receiver operating characteristic curve calculated for each group at 3 months post-treatment. A: This figure presents Kaplan-Meier survival curves illustrating the 3-month survival probabilities across the study groups stratified by serum alpha-fetoprotein (AFP) levels (low AFP group, medium AFP group, and high AFP group). The curves visualize differences in survival outcomes among the groups over the 3-month follow-up period; B: This figure displays receiver operating characteristic curves with corresponding areas under the curve values calculated for each group (low AFP group, medium AFP group, and high AFP group) at 3 months post-treatment. The areas under the curve values quantify the diagnostic performance of serum AFP levels in predicting outcomes at the 3-month time point. AFP: Alpha-fetoprotein; AUC: Areas under the curve.
