Notes: CI = confidence interval; FDR = false discovery rate correction: a corrected p value that is adjusted for multiple comparisons. The associations with p values less than the FDR-corrected p values are considered to survive the adjustments for multiple comparisons. STW-speed = gait speed during single-task walking; TMT, Trial Making Test; WWT-speed = gait speed during walking while talking. Higher scores in TMT interference and TMT-A indicate poorer function.
