Table 5.

The association of the presence of chronic low back pain with cumulative ultra-short time-to-echo disc sign (UDS) score on UTE and the cumulative disc degeneration score on T2-weighted magnetic resonance imaging (MRI).

Presence of Chronic Low Back Pain
MRI Cumulative Scores No
(n = 66, 64.7%)
mean (range,SD)		 Yes
(n=36, 35.2%)
mean (range,SD)		 p-value
UDS Score 0.5 (0–3, 0.7) 1.05 (0–5, 1.4) 0.009*
T2-weighted Disc
Degeneration Score		 7.5 (3–10, 1.8) 8.1 (4–12, 1.9) 0.12

Note, the analysis represents 102 subjects. Cumulative scores represent summated individual disc scores from L1/2 to L5/S1.

SD: standard deviation
