Following publication of the original article [1], the authors noticed an error in Fig. 2, and some cropping of the text in Fig. 3. Presented here are the updated Figs. 2 and 3. The original article has been updated.

Matching covariate standardized mean differences after large-scale propensity score matching (PSM) and cardinality matching (CM). Fine balance: exact marginal distributional balance. Violin plots illustrate kernel probability density; the width of the shaded area represents the proportion of observations with the corresponding y-axis value
