Model-adjusted means for each test period, calculated at the mean age and mean attendance for each period.
Comparisons between baseline and each test period, and between test periods, were adjusted separately for each outcome using Hochberg adjustment (44).
Estimates for participants without assistive devices; use of these devices adds 0.46 (±0.06) seconds to all testing times. Model-adjusted means for each test period, calculated at the mean age and mean attendance for each period. Means compared between test periods, within each outcome, and adjusted for multiple comparisons using Hochberg adjustment.
