Architectural parameters of the samples (n = 10)

Parameters^a	Mean	S.D.	Range
VF^b	0.243	0.044	0.190 – 0.320
ρ_app (g/cm³)	0.462	0.085	0.363 – 0.610
Tb.Th. (mm)	0.184	0.034	0.133 – 0.235
Tb.Sp. (mm)	0.606	0.080	0.467 – 0.700
SMI (−)	0.568	0.391	−0.131 – 1.078
Conn.D. (1/mm³)	5.410	2.674	2.611 – 11.449
DA (−)	1.828	0.195	1.603 – 2.265

VF = volume fraction; ρ_app = apparent density; Tb.Th. = trabecular thickness; Tb.Sp. = trabecular spacing; SMI = structure model index; Conn.D. = connectivity density; and DA = degree of anisotropy.
