^aRemarks: Displayed is the fraction of treated individuals satisfying the common support condition on all treated individuals in the respective sample. On support are those individuals, whose propensity score is not smaller than the smallest and not larger than the largest propensity score in the respective group of non-treated individuals. Treated observations, who are off support, are not used in the matching analysis to estimate treatment effects.
