Comparison of serum levels of (a) interleukin (IL)-6 and (b) matrix metalloproteinase (MMP)-1 between control subjects and participants with low back pain (LBP). Levels in participants with LBP were analyzed by pooling the epidural steroid injection and surgery cohorts. Analysis of serum levels of (c) IL-6 and (d) MMP-1 in participants with LBP based on disease severity, classified by Pfirmann grade, where grade 2 represents low disease severity and grade 5 represents high disease severity. Each symbol represents values from a single subject; midline represents the mean; and error bars represent the standard error. *p < 0.05, **p < 0.005
