Fig. 3. Hemodynamic responses to the Stroop test in patients with HF, after OCT, or after CABG surgery. Values are means for successive 1-minute periods from baseline (minute 0) through the Stroop test and recovery. The line on the time axis shows the period of Stroop testing. Stroop (and baseline) values are adjusted by analysis of covariance to a common baseline, and recovery values are adjusted for the final minute of Stroop testing. Lines are broken where the baseline for covariance adjustment changes. The line on the time axis shows the period of Stroop testing. *OCT group differs from the CABG group; +OCT group differs from the HF group.
