Figure 2. Scatterplots between leukocyte telomere length and the cognitive performance, stratified by sex.

Figure 2.

A linear relationship and the corresponding 99.5% confidence interval (shaded region) is modeled to depict the association between z-scores for leukocyte telomere length and working memory, episodic memory, semantic processing, and information processing speed, separately for aging LLFS males (n = 752) and females (n = 883) in the cognitively unimpaired group (n = 1,613). The z-score computed for each cognitive domain adjusts for age, generation, education, and country, while the z-score for leukocyte telomere length adjusts for the aforementioned in addition to lymphocyte percentage.
