Limitations
MDD
Limitations of our study include the need for more active controls, the size of the sample, the short duration of treatment, and strict inclusion and exclusion criteria that may limit the generalizability of the results. Additional demographic factors (e.g., the age of participants and the proportion of the first episode) may have further affected the results of our study. Therefore, more evidence could be required to prove the efficacy of ansofaxine in older MDD patients.
