  1. Data are presented as means ± SD. HC, healthy controls; CVC, older elderly men with cardiovascular comorbidities; LLD, older elderly men with late-life depression; LLD + CVC, older elderly men with late-life depression with cardiovascular comorbidities; TNE, total number of errors; PE, perseverative errors; CLR, conceptual level response; NCC, number of categories completed; TCC, trials to complete the first category. aThe direction of '>’ shows the performance from better to worse; bFisher's least significant difference post hoc test; cKruskal-Wallis test; dMann-Whitney U test.
