The association of the ultra-short time-to-echo disc sign (UDS) with various imaging phenotypes on magnetic resonance imaging (MRI).

Presence of UDS (Intervertebral Disc-Specific)
MRI Variables	No (n = 469, 86.8%) n (%)	Yes (n=71, 13.2%) n (%)	p-value
Disc degeneration	219 (46.6%)	60 (84.5%)	< 0.001*
Disc displacement‡	200 (42.6%)	59 (83.1%)	<0.001*
High-intensity zones	118 (25.1%)	25 (35.2%)	0.08
Endplate abnormalities	147 (31.3%)	27 (38.0%)	0.22
Modic changes	67 (14.3%)	34 (47.8%)	<0.001*
Spondylolisthesis	3 (0.63%)	4 (5.63%)	0.007*

Note, the analysis entails the assessment of 540 lumbar intervertebral discs representing 108 subjects.
