Note: Means are presented, where d indicates the treatment condition and B represents the overall mean for each propensity score stratum. t tests indicate that mean propensity scores did not differ between non-treated (d = 0) and treated (d = 1) respondents for any of the strata in Table 4 (p < .001; see Brand and Xie 2010:281).
