  1. VO2, volume of oxygen; HAM-D, Hamilton rating scale for depression; t test and Pearson coefficient summarized associations between participant characteristics and global cognitive performance where appropriate. Data summarized using mean (with standard deviation) unless otherwise stated. *One-way analysis of variance (ANOVA) (with F value) performed for global cognition across ethnicity and cardiac history groups, respectively.
