U Mann Whitney-test: p < 0.05; SD, standard deviation; * p < 0.05 between cortical and marrow compartment either at diaphysis (Cort-dia vs Marrow-dia) and metaphysis (Cort-meta vs Marrow-meta) topographic regions (vertical); # p < 0.05 between diaphysis and metaphysis either at cortical (Cort-dia vs Cort-meta) or marrow compartment (Marrow-dia vs Marrow-meta) (horizontal).
