  1. Sample size, n = 63. Data are expressed as odds ratios ±95% confidence intervals (CI) as assessed by binary logistic regression analysis
  2. Group A type 2 sclerotic Modic change, Group B type 2 Modic change, Group C no Modic change
  3. All covariates included in binary regression models were as follows: model 1a: groups A1 and C1, model 2a: groups A1 and B1, model 3a: groups B1 and C1
