  1. Note: BV/TV is bone volume fraction; Tb.N is trabecular number; Tb.Th is trabecular thickness; Tb.Sp is trabecular separation; SMI is structure model index; Conn.D is connectivity density; BS/BV is specific bone surface; vBMD is average volumetric bone mineral density and mBMD is material bone tissue mineral density. Difference % = (AIS − control)/(control) %.
