Table 3. Size-standardized pQCT-derived true CSG property means from the tibial midshaft among living males and females.
All male data are taken from Shaw and Stock (15), and all male data were size-standardized following the methods outlined in Shaw and Stock (15). Imax, maximum second moment of area, quantifies maximum bending/torsional rigidity; Imin, minimum second moment of area, quantifies minimum bending/torsional rigidity; CA, cortical bone area; %CA, percent cortical bone area (relative to total subperiosteal area).
