Age-dependent response to RCF. a Principal component analysis (PCA) of the biomarkers tested in the study for the three time points and similar analysis performed in young (n = 37, 26.5 ± 3.2 years, 20–30) and older participants (n = 41, 68.1 ± 8.6 years, 52–85). b Age-related adaptations to fasting and c the benefits of fasting on CRP and systolic BP were tested after stratification based on age [young (20–30), middle-aged (50–64) and old (65–85)]. d Similar analysis as in c showing IL-6, d-dimer and OPG. ap = 0.005 significant difference with pre-fasting 65–85 (no difference with all groups together). bp = 0.03 significant difference with pre-fasting 65–85 (no difference with all groups together)
