Statistical Analysis
For baseline characteristics analysis, variables were properly described as means and SDs, medians and IQRs, or counts and frequencies. For normally distributed data, unpaired The primary outcome (percentage PANSS score change) was evaluated by a mixed model for repeated measures (MMRM), which is a better approach than both last observation carried forwardStatistical significance was defined at a 2-tailed α level of .05. No correction for multiple testing of exploratory outcomes was applied. SPSS Statistics version 26.0 (IBM) and R version 4.2.1 (The R Foundation) were used for statistical analyses. All available postbaseline outcomes measures were included in the analysis.
