Table 4 Balancing test for pre-treatment covariates conditional on the propensity scores

Note: Mean Bias (median bias) refers to the mean (median) absolute bias across all covariates used in the specification of the propensity scores. For each covariate it is defined as the ‘standardized’ bias defined as the difference of the sample means in the treated and untreated samples as a percentage of the square root of the average of the sample variances in the treated and untreated groups. P-value-chi2 is the p-value of the likelihood-ratio test of the joint insignificance of all the regressors before and after matching.
