*, P<0.001. uEP, upper endplate; lEP, lower endplate; both, involvement of both upper and lower endplates; %, total EFPs at each vertebral level divided by total EPFs of this male database, i.e., n=140. u/l ratio, ratio of uEPF/lEPF at each vertebral deformity (VD) grade. % both, percentage of EPF involving both uEP and lEP at each VD grade.
