^aIndicates a variable is binary. ^bIndicates a variable is not balanced after matching (p value < 0.05 or standardized bias > 5%). Abbreviations: U, unmatched; M, matched; % bias: percent standardized bias; CES-D, Center for Epidemiological Studies-Depression 8 item scale. The t-test p value refers to the p value from the difference in means between the treated and control groups before and after matching. The V(T)/V(C) column presents the ratio of a continuous variable’s variance for the treatment group over the variance for the control group. Additional covariates in the matching procedure: marital status, firm size, industry, survey year, regional Census division, additional categories for variables with missing values, and the first 10 principal components of the European ancestry genetic data. We used kernel-based propensity score matching with a bandwidth of 0.06. Unmatched control observations = 11,629; Unmatched treated observations = 399; Matched control observations = 11,559; Matched treated observations = 375.
