  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
First, the sample size was relatively small. Second, the diagnostic criteria for depression which are typically used in clinical trials were not used as an inclusion criterion. Third, antidepressant use at baseline was common in our population.
