Gamma: odds of differential assignment due to unobserved factors.
Q_mh+: Mantel-Haenszel statistic (assumption: overestimation of treatment effect).
Q_mh−: Mantel-Haenszel statistic (assumption: underestimation of treatment effect).
p_mh+: significance level (assumption: overestimation of treatment effect).
p_mh−: significance level (assumption: underestimation of treatment effect).
