Chi-squared test of proportions for the self-reported ethnicity marginal effects showed mixed evidence, with no significant difference from the null expectation in CATIE (χ 2 statistic = 1.214; χ 2 p -value = 0.865) and a modestly significant result in STAR*D (χ 2 statistic = 3.100; χ 2 p -value = 0.039).
