Results of linear regression models for our dataset. This figure shows the modeled effects of age group and task performance on RSFC between each pair of seed ROIs. The FD covariate effects were not shown for simplicity. Shadow areas and error bars indicate 95% confidence intervals. The asterisks indicate significance level after FDR correction within each task (i.e. 8 times for each task), * P < 0.05, ** P < 0.01, *** P < 0.001.
