2. Fig. 1
MRI showing the classification of shapes according to the morphological presentation of SN. a) shows the indented shape SN at caudal endplate (EP) of L2 disc level; b) shows the sharp shape SN at caudal EP of L2 disc level; c) shows the round shape SN at caudal EP of L2 disc level; d) shows the rectangular shape SN at rostral EP of L2 disc level; and e) shows the irregular shape SN at caudal EP of T12–L1 disc level and both rostral and caudal EP of L3 disc level.

4. Fig. 3
Bar chart showing the percent prevalence of the relative size of SN per lumbar disc level. A yellow dashed line is inserted to illustrate the reverse pattern of the SN size across the lumbar disc levels that prevalence of small SN peaked at L3. Percent values are illustrated in labels.

5. Fig. 4
Bar charts showing the percent prevalence of the location of endplate zone of SN per lumbar disc level. A yellow dashed line is inserted to illustrate the reverse pattern of the relative location of SN across the lumbar disc levels that prevalence of middle located SN peaked at L3. A green dotted line is inserted to illustrate the decrease prevalence in anterior and anterior-middle located SN from the upper to the lower lumbar disc levels. Percent values are illustrated in labels.

7. Fig. 6
Graph showing the multivariable ordinal logistic regression model showing the odds ratio (OR) associated with the increase in DD severity with the presence of “Typical SN” and “Atypical SN” at both rostral and caudal endplates. Model adjusted for gender, age, BMI, smoking status, presence of disc displacement, and HIZ. (Note: If the range of 95% CI of the OR value does not cross the value of 1 [the green dashed line], the association is significant).
