Reporting Groups
  Description
Placebo Participants randomized to the placebo group received capsules that contained soybean oil with 1% fish oil so that it was flavored to taste and smell similar to the fish oil capsules.
Omega-3 Fatty Acids Participants randomized to the omega-3 FA group received capsules in the form of fish oil concentrate (triglyceride form) at a daily dose of 6 grams (1.95 grams of EPA and 1.45 grams of DHA).

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.
The study was powered to enroll twenty six subjects (13/group), the number needed to see a difference in Hamilton Depression Rating Scale (HDRS) over 3 months. The Montgomery Asberg Rating Scale has good validation with the HDRS and is more sensitive to emotional change than the HDRS.
