Notes
Relative leucocyte telomere length measured by quantitative PCR. This measure is a ratio of telomere repeat copy number to single copy gene (
HBB) copy number, relative to a standard sample. Full details of the methodology used to measure telomere length can be found in Codd, V. et al (
https://doi.org/10.1101/2021.03.18.21253457.)
Please note that this is a raw measure and has not been adjusted to remove technical variation. We strongly recommend that for any analysis, researchers use the technically adjusted measures provided in
Field 22191 (Adjusted T/S ratio) or
Field 22192 (Z-adjusted T/S). Details of the technical adjustment can also be found in Codd, V. et al (
https://doi.org/10.1101/2021.03.18.21253457.)
