Abbreviations: Den DF, denominator degrees of freedom; HAM-A, Hamilton Anxiety Rating Scale; Num DF, numerator degrees of freedom; MADRS, Montgomery-Asberg Depression Rating Scale.
DFs were calculated using the Satterthwaite approximation. Repeated measures nested within block were modeled with a compound symmetry variance structure and a random subject effect.
