Influence of therapeutic plasma exchange on liver-transplant-free survival in a propensity-score-matching analysis. A love plot showing the variables used for the propensity score matching (PSM) and their balance before and after PSM. All the variables, except for age, achieved proper balance (standardized mean difference < 0.1) after matching (A).
