Percent change (% change) in cardiovascular and cerebrovascular variables in response to the Stroop color and word test before (control) and after (indomethacin) administration of indomethacin. Values are expressed as means % change ± SD, and individual data points are provided. A: percent change in mean arterial blood pressure (MAP). B: percent change in middle cerebral artery blood velocity (MCAv). P value indicates a significant difference between young (n = 23; 10 M, 13 F) and older adults (n = 21; 11 M, 10 F) (independent-samples t test or Wilcoxon rank-sum test) or within groups across conditions (dependent-samples t test or Wilcoxon signed-rank test) in response to the Stroop color and word test.
