Abbreviations: SE standard error, CI confidence interval, ES effect size, CF cognitive functioning, VLT verbal learning test, TMT trail making test, SST stop-signal task, SSRT stop-signal reaction time, LDST letter digit substitution test. * Effects are reported as intervention group vs control group as the control group served as a reference group. a TMT – time B-A in sec was log transformed. b SST – SSRT in ms was square root transformed
