2. Fig 1
Mean z-scores for individual and the overall (global) cognitive domains showing longitudinal trends in cognitive performance for each study group from baseline to 3-, 12-, and 36-month follow-up. The z-scores have been standardized relative to the baseline performance of the heart-healthy controls, whose mean baseline value is therefore zero. The z-scores have been adjusted as described in Methods. Error bars indicate the limits of the 95% confidence interval for the mean of each measure.

3. Fig 2
Comparison of the degree of change in mean z-scores from baseline between the on-pump coronary artery bypass graft surgery group (CABG) and off-pump CABG surgical group. Scores are based on the means of individual within-patient changes from their own baseline. To compare changes from each group’s starting point, baseline values are set at zero for both groups. Error bars indicate the limits of the 95% confidence interval for the mean change of each measure.

4. Fig 3
Comparison of the degree of change in mean z-scores among the three groups with coronary artery disease (HD) and the heart-healthy controls (HHC) from baseline to each follow-up point. To compare changes from each group’s starting point, baseline values are set at zero. Error bars indicate the limits of the 95% confidence interval for the mean change of each measure.
