Figure 3. Intervention group age change. Participants in the treatment group (n = 18) scored an average 2.04 years younger at the end of the program, measured by the Horvath DNAmAge clock, as compared to the same individuals at the beginning (p = 0.043 for within group change). Of 18 participants included in the final analysis, 8 scored age reduction, 9 were unchanged, and 1 increased in methylation age.
