  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
Low power to detect statistically significant effects of the interventions on outcomes; Inability to examine predictors of responsiveness because of the small sample size and the large number of predictors of response.
