Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment ran from January 2008 to January 2010. All patients were recruited in one surgical clinic at Dartmouth Hitchcock Medical Center.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Forty-three women were identified as potential study participants from May to December 2009. Three were excluded, because two were unable to consent and one was under 18 years old. Nine women declined to participate. Of the remaining 31 patients (72.1% of those identified), all completed the informed consent, the surgery, and the follow-up process.

Reporting Groups
All Participants All participants were randomized to have one breast reduced using the harmonic scalpel and the other breast using electrocautery.

  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
We made a first analysis after 26 (intended enrollment 50) patients were enrolled and a result was strongly suggested. While the analysis was refined, 5 more patients enrolled. The study was then stopped after 31 patients enrolled.
