Participants received active or sham CR plus active or sham tDCS for 8 weeks, followed by semi-annual booster sessions and online CR between visits. Cognitive assessments occurred at baseline, 8 weeks, and yearly. Elastic net regression identified relevant markers and baseline variables associated with the 8-week cognitive change. For selected markers, treatment*marker interactions were tested using multivariable linear regression adjusted for relevant demographic, clinical, and genetic covariates. Significant interactions were further examined using likelihood ratio tests in linear mixed-effects models across follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In 271 participants, angiopoietin-2, endocan, and VCAM-1 were identified as relevant markers.
