Table 3 Differences in percent change in pain severity (NRS scores) Modic type I vs. no Modic changes, Modic type I vs. Modic type II and Modic changes present (both types I and II) and Modic changes absent

From: Are the presence of MODIC changes on MRI scans related to “improvement” in low back pain patients treated with lumbar facet joint injections?
