Sample Collection & Storage Checklist (v.1) – guidance for key metrics to track related to sample collection, storage, and processing
Determining sample size in cross-sectional studies: The effect of intra-class correlation coefficient (ICC) on statistical power and required sample size based on various diference in TL. For questions/comments on this resource, please contact Simon Verhult (firstname.lastname@example.org).
Determining sample size in longitudinal studies: Power to detect a 33% change of telomere shortening rate, up or down, with p<0.05 relative to a baseline shortening rate of 25 bp/year, for a four-year and eight-year follow-up period.
