Association between sleep parameters and longitudinal shortening of telomere length
Figure 2. Degree of change in telomere length over two years in each group. Participants were grouped according to initial diagnosis (A), sleep duration (B), sleep latency (C), and sleep efficacy (D). Abbreviations: LTL: leukocyte telomere length; CU: cognitively unimpaired, MCI: mild cognitively impaired; ADD: Alzheimer’s disease dementia; h: hours. P-value for the Kruskal-Wallis test. *P < 0.05 compared with the first group (sleep ≥7 h or sleep efficiency ≥85%).
