TABLE 4.

Results of Mann–Whitney comparisons between exercised and rested groups for canals with Ca.Ar >0.002 mm².

Bone	Ct.Ar		N.Ca		Tt.Ca.Ar		N.Ca/Ct.Ar		Tt.Ca.Ar/Ct.Ar
	U	p	U	p	U	p	U	p	U	p
Rib	21	0.69	15	0.69	16	0.81	17	0.94	14	0.58
Tibia	6	0.12	8	0.24	4	0.06	10	0.41	5	0.08
Metacarpal diaphysis	12	0.65	16	0.93	3	0.04	16	0.93	4	0.06
Metacarpal metaphysis	19	0.94	6	0.07	0	0.01	5	0.05	0	0.01

Note: U values tend towards 0 as the overlap between the two groups' rank distributions decreases to 0. All groups have n = 6 except rested tibia and rested metacarpal diaphysis which have n = 5.
