Fig. 1: Standardized mean difference in PSM models.

From: Propensity score matching analysis of valve-sparing versus aortic root replacement in type A aortic dissection patients

Fig. 1

This figure presents the standardized mean differences (SMD) for various covariates related to the study, both before and after propensity score matching (PSM). Each panel represents a different variable: distance, no or mild aortic regurgitation, ACC time, moderate, Marfan syndrome, aortic root diameter, bicuspid aortic valve, BMI, AGE, and severe AR (both unadjusted and adjusted). The SMD values indicate the degree of imbalance between the groups. Covariate balance was evaluated by analyzing the standardized difference of means, with an absolute value of the mean difference <0.1 considered indicative of successful matching. No_or_Mild no or mild aortic regurgitation, AR aortic regurgitation.
