  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
Small, single-institutional study. Smaller clinical trials are prone to imbalances in patient characteristics across treatment arms. t tests applied to small studies can be unduly influenced by data that contain outliers or are skewed.
