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. ccx triglyceride' refers to measurements made at the GRC (see description of triglyceride -grc' -- file 002, card 1 & true triglyceride' -- file 002, card 4 & triglyceride-bs' -- file 002, card 2). From 1991 to the present, triglyceride has been measured in plasma using the Abbott CCX method.

    Other triglyceride measurements (see above) measured in different sample types and with different methodologies are not equivalent. The ccx triglyceride' 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 consistancy (for more information please contact investigators).
