There is no significant increase/decrease in the rate of surgery between the years 2007 and 2012 for patients with back pain (P = .061).
- Figure 5
(A) There is a positive correlation between the rate of injections and the rate of surgery for all states. The P value for this correlation is less than .0001. (B) As with the general population, there is a positive correlation between the rate of epidural steroid injection (ESI) and rate of surgery among patients older than 65 years. The P value of this correlation is less than .0001.
