From: Does a dose-response relation exist between spinal pain and temporomandibular disorders?
Spinal pain as independent variable: Odds ratios and 95% confidence intervals for TMD symptoms and headaches. Odds ratios (ORs) and 95% confidence intervals (CIs) for presence of frequent symptoms in the jaw-face region and headaches among subjects with infrequent spinal pain (SP-1), subjects with frequent spinal pain (SP-2) and patients with disabling spinal pain attending a rehabilitation programme (SP-3), compared with controls (SP-0). ORs and 95% CIs were calculated with binary logistic regression analysis, adjusting for age and sex.
