The brain metrics with significant (p < 0.05) LVs from the mean-centered PLS analyses and bPLS analyses. Analyses with two significant LVs are denoted with a. The combined analysis with SC weighted degree, FC weighted degree, and SC–FC coupling with age as the dependent variable (combined bPLS of SC, FC, and SC–FC coupling with age) identified SC as the dominant predictor of age, as marked by b. bPLS analyses with age and all three attention measures included were also conducted (Extended Data Table 2-1) and compared with the separate analyses (Extended Data Tables 2-2, 2-3). SC, structural connectivity; FC, functional connectivity.
