  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
Our study had several limitations. Since we were studying veterans, the patients were predominantly men, and extrapolation of our findings to women must be done with caution.Changes in therapeutic agents have occurred since the design of our protocol
