Specific to this Data Element:
    Descriptive history:
    Triglycerides have been measured continuously since 1959. During this time, different methods and different laboratories have provided the triglyceride values. triglyceride-bs' refers to measurements made at the Bioscience Laboratories (see description of triglyceride -grc' -- file 002, card 2 & true triglyceride' -- file 002, card 4 & ccx triglyceride' -- file 002, card 4). A brief chronology of the triglyceride-b' measurement follows:

    Dates Sample Type Method
    1959 - 1983 serum Kissler
    1983 - 1985 serum Cobas (Roche reagent)

    N.B. -- from 1991 to the present, triglyceride measurements have been measured in plasma using Abbott-CCX analyzer (see ccx triglyceride'-- file 002, card4)

    Triglyceride measurements made from different sample types and methodologies are not equivalent. The triglyceride-grc' values in this file are entered as is. Longitudinal and cross-sectional analyses made over time periods where changes occurred in the methodology require adjustment to achieve equivalency (for more information please contact investigators).

    Frequency of data collection:
    From 1981 to 1993 the triglyceride values were measured only on those subjects known to have an elevated triglyceride or cholesterol in the past or on the initial visit.

    Inclusion/exclusion rules:
    None.
