Prevalence of hyperdense mineralized foci in all motion segments with and without ectopic mineral bridging of the IVD as determined by µCT

IVD	All available motion segments (n = 18 spines)
	Hyperdense foci
	Yes	No	Total
Bridge	70	13	83
No bridge	40	48	88
Total	110	61	171

Two-sided, Fisher’s exact test (α = 0.05); P < 0.000 1

Data are binary counts (yes/no) for the presence of hyperdense foci within individual motion segments related to the presence or absence of ectopic mineral bridging of the IVD, irrespective of categorization based on the diagnostic criteria for DISH
