Table 1.

Results from mixed models comparing µCT to DTS and HRCT topography measurements at superior endplates. The symbol ∪ indicates that the depth measurements from AP and LM views were pooled before calculation of the distribution statistics. The symbol ā indicates that the distribution statistics from AP and LM views were averaged. For ease of comparison with DTS/HRCT averages, µCT averages are presented below each parameter in parentheses.
