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 mainly from the Legacy Community Health Center and Thomas Street Clinic of the Harris County Hospital District and from Houston Area Community Services and private clinics. Recruitment period: January 2004 to September 2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
If potential subjects were taking nutritional supplements or lipid-lowering drugs, these were discontinued for washout for 6 weeks - baseline fasting lipid levels were then measured to determine eligibility prior to randomization.

  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
High dropout rate, especially by loss to follow-up (with no explanation). Flushing was common among patients taking niacin, and this (with transportation and socio-economc problems) could have contributed to the high drop-out rate.
