Likelihood changes over time were compared by means of generalized estimating equations including Brain Age Gap Estimation as a covariate. Results of estimated marginal means analyses conducted for the functional trajectory, time point, and classifier factors were visualized. See eTable 11 in Supplement 1 for a tabular representation of results.
