Table 3: Results from the regression model on the association between vertebral endplate changes and chronic LBP, in which all patients with LBP (240) were included^{^a}
Crude Analysis Adjusted Analysis
OR (95% CI) P OR (95% CI)^{^b} P
Vertebral endplate changes 0.43 (0.14–1.29) .132 0.31 (0.10–0.95) .041
↵a The maximal model included sex, age, body mass index, lifetime smoking, highly intense physical activity, disk degeneration, and the interaction between disk degeneration and vertebral endplate changes.
↵b Adjusted by disk degeneration.
