Change of CDSS sum score. Linear mixed effects model curves. Linear slopes for the randomization groups generated based on linear mixed effects models, CDSS sum score output, as displayed in Table 1 for olanzapine, quetiapine, risperidone and ziprasidone, respectively. The curves are confined to the first 300 days because the major bulk of data is obtained before 300 days. CDSS = the Calgary Depression Scale for Schizophrenia.
