  1. Notes: Non-exp = non exposed, Exp = exposed, Mean % |bias| mean standardized % absolute bias, Treated = N in the treated group, Control = N in the control group
  2. Mean standardized bias is the % difference of the sample means in the treated and non-treated sub-samples as a percentage of the square root of the average of the sample variances in the treated and non-treated groups [34]
  3. p-values are the p-values from a likelihood-ratio test of the joint significance of all the regressors
