mTL in various tissues. (A) mTL from muscle, fat, leukocytes, and skin from all samples as measured by Southern blot. (B) mTL for muscle, fat, leukocytes, and skin by sex. (C) mTL difference between leukocyte–muscle and skin–muscle to estimate interindividual telomere attrition after controlling for “early development” TL. Box plots showing the 25th and 75th percentiles as the upper and lower half of each box along with the 10th and 90th percentiles as upper and lower error bars plus individual outliers.
