The explaining effect of diurnal slope (n = 62) on the associations between depressive symptoms and cognitive performance (only beta's presented).

For all measures: Beta's are corrected for age, gender, education and IQ.Higher values indicate worse performance.95%CI: 95% confidence interval.†Regression coefficients (beta's) indicating the mean change in cognitive performance, associated with an increase of 13 points IDS-SR score.£Regression coefficients (beta's), after inclusion of diurnal slope in the model.Diurnal = diurnal slope; Speed = psychomotor speed; Process = speed of information processing; Attention = attentional switching; Mean = mean z-score of all 6 cognitive domains; % change = difference score divided by startvalue †; 95%CI = 95% confidence interval.
