  1. Number of slices measured for length and participants measured for cross-sectional area and volume measurements, intraclass correlation coefficient (ICC), and accompanying 95% confidence intervals (CI). Due to absence of dural sac at certain otherwise measured slices, a lower number of slices were measured. Participants with unequal start- and end-slices were excluded from the analyses, leading to varying numbers of included participants.
