The relationship between regional pain with or without neuropathic symptoms and chronic widespread pain

This study was performed to test whether the risk of developing chronic widespread pain (CWP) in those with regional pain was augmented in those with symptoms of neuropathic pain (NP). Persons free of CWP completed the Douleur Neuropathique 4 (scores ≥3 indicating NP); demographics; Hospital Anxiety and Depression scale; Pittsburgh Sleep Quality Index; and pain medications. Participants were classified as having no pain, regional pain with no symptoms of NP ( JOURNAL/jpain/04.02/00006396-201908000-00014/math_14MM1/v/2019-07-21T190841Z/r/image-tiff ), or regional pain with symptoms of NP (NP). At the 12-month follow-up, participants with CWP were identified. Logistic regression estimated the odds ratio, with 95% confidence intervals, of CWP in the JOURNAL/jpain/04.02/00006396-201908000-00014/math_14MM2/v/2019-07-21T190841Z/r/image-tiff and NP groups compared with no pain, and NP compared with JOURNAL/jpain/04.02/00006396-201908000-00014/math_14MM3/v/2019-07-21T190841Z/r/image-tiff . Partial population attributable risks estimated the proportion of CWP attributable to baseline JOURNAL/jpain/04.02/00006396-201908000-00014/math_14MM4/v/2019-07-21T190841Z/r/image-tiff or NP exposure. One thousand one hundred sixty-two participants completed the baseline DN4 and provided pain data at follow-up: 523 (45.0%) had no baseline pain, 562 (48.4%) JOURNAL/jpain/04.02/00006396-201908000-00014/math_14MM5/v/2019-07-21T190841Z/r/image-tiff , and 77 (6.6%) NP.
