  1. Note: pBV/TV is plate bone volume fraction; rBV/TV is rod bone volume fraction; P-R ratio is the ratio of plate bone tissue to rod bone tissue; pTb.N is plate trabeculae number density; rTb.N is rod trabeculae number density; pTb.Th is mean trabecular plate thickness; rTb.Th is mean trabecular rod thickness; pTb.S is mean trabecular plate surface area; rTb.L is mean trabecular rod length; R-R Junc.D is rod-rod junction density; P-R Junc.D is plate-rod junction density and P-P Junc.D is plate-plate junction density. Difference % = (AIS − control)/(control) %.
