  1. Sample size, n = 196. 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 1: groups A and C, model 2: groups A and B, model 3: groups B and C
