Percentage of MRI grade of disc degeneration in vacuum phenomenon shape type and distribution analyses. The percentage of MRI grade (Pfirrmann’s classification [10]) of disc degeneration in vacuum phenomenon (VP) shape type (a) and distribution (b) analyses. *P < 0.0025, #P < 0.002 (by Bonferroni correction). The percentage of advanced degenerative stage discs (Pfirrmann grades IV and V) of each group is indicated by a bracket
