Outcome Measures

Primary Outcomes (1)

  • Cross-sectional analyses database

    The only protocol specific to the PCLS study is the collection of blood sample for risk factor determination and storage in the PBRC archive bank, only to be invoked in cases where studies do not include a blood draw as part of their protocol. The PCLS represents an effort to utilize a data collection over the last twenty years during the clinical research studies for cross-sectional analyses, as well as followed prospectively for the development of a variety of health-related outcomes.
