Table 1:

Effect of treatment (CANA) or high blood glucose (BG) on selected outcome measurements (mean ± SD) from the evaluations of femur mid-shafts (cortical bone) and distal femur metaphysis (trabecular bone). CANA-treatment normalizes a bone parameter if the CANA vs. Low BG comparison is not significant (NS). p<0.05 (p<0.1).

a

P-value from Dunn’s test because only Ct.Th of TH – Low BG did not pass normality, but the residuals did pass normality.

b

P-value from Kruskal-Wallis test because residuals did not pass normality

c

P-value from Kruskal-Wallis test because the SDs were significantly different among the 3 groups
