Results

Add-on brexpiprazole had the following effects on sleep architecture in patients with schizophrenia.
The fraction of stage N2 increased by 14.0% (p = 0.018), and the duration increased by 49.9 min (p = 0.018). The fraction of stage N3 increased by 0.7% (p = 0.027), and the duration increased by 2.5 min (p = 0.034). Additionally, the fraction of stage REM sleep was reduced by 10.0% (p = 0.018), and the duration was decreased by 33.8 min (p = 0.018).
