Table 1.

MicroCT scans were successfully acquired for all the samples at P7 (N=123), and for most samples at P21 (N=115, excluding 2 samples due to animal death and 6 samples due to scanner failure). Quality check (QC) was performed to remove samples with severe motion artifacts. This table shows the QC result by group crosstabs for P7 and P21 sample sets. Chi-square test indicated no significant relationship for QC results between treatment groups.
