- Abbreviations: LOCF = last observation carried forward; LS mean = least squares mean; MADRS = Montgomery-Åsberg Depression Rating Scale; MMRM = mixed-effects model repeated measures; OLZ = olanzapine group; PBO = placebo group; SD = standard deviation; SE = standard error.
-
a within treatment p values are from t-tests on LS Mean change; p values and LS Mean for change from baseline are from analysis of covariance model: change = treatment + baseline + geographic region (Type III sums of squares).
-
b within treatment p values are from t-tests on LS Mean change; p values are from Type III sums of squares and Kenward-Roger approximation as denominator degrees of freedom; MMRM analysis: change = treatment + baseline + geographic region + visit + treatment * visit.
-
c MADRS-6 subscale contains 6 individual MADRS items: Apparent Sadness, Reported Sadness, Inner Tension, Lassitude, Inability to Feel, and Pessimistic Thoughts, considered to be “core” depressive symptoms.
