  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

Limitations of the current study included:

  1. Reliance on self-reports to measure adherence
  2. Study population almost exclusively male (reflecting the demographics of people who call Fenway Health's hotline after an acute sexual exposure)
