  Participant Flow

Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Subjects were recruited from March 2008 though February 2011. They were recruited through flyers distributed around McLean Hospital (Belmont, MA), referral by clinic doctors and direct recruitment on the hospital's units.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Enrolled participants are excluded from statistical results if they had baseline Hamilton Depression Rating scores under 17 or co-morbid disorders.

Reporting Groups
  Description
Bipolar Disorder Active LFMS Treatment Subjects with bipolar depression receiving active treatment with the Low Field Magnetic Stimulation Device.
Bipolar Disorder Sham LFMS Treatment Subjects with bipolar depression receiving sham treatment with the Low Field Magnetic Stimulation Device. The sham treatment is identical to the active treatment, with the exception that subjects to not receive the active stimulation.
Major Depressive Disorder Active LFMS Treatment Subjects with major depression receiving active treatment with the Low Field Magnetic Stimulation Device.
Major Depressive Disorder Sham LFMS Treatment Subjects with major depression receiving sham treatment with the Low Field Magnetic Stimulation Device. The sham treatment is identical to the active treatment, with the exception that subjects to not receive the active stimulation.

  Baseline Characteristics

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.

  Serious Adverse Events


  Other Adverse Events


  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
A limitation of the current trial was that it was underpowered to detect moderate but clinically significant benefits of LFMS in diagnostic subgroups.
