Table 6.
Unadjusted and adjusted odds ratios comparing subject characteristics reporting multiple persistent pain conditions
| Model 1 | Model 2 | Model 3 | |
|---|---|---|---|
| Odds Ratio (95% CI) | Odds Ratio (95% CI) | Odds Ratio (95% CI) | |
| Control | 1.0 (reference) | 1.0 | 1.0 |
| TMD without WPT | 6.5 (2.7, 15.6) | 5.8 (2.4, 14.2) | 3.3 (1.3, 8.4) |
| TMD with WPT | 32.5 (13.7, 77.0) | 23.1 (9.6, 55.9) | 8.4 (3.1, 22.8) |
| Age-z | NA | 1.8 (1.3, 2.4) | 1.9(1.4, 2.7) |
| Somatic symptoms-z | NA | NA | 2.3 (1.5, 3.6) |
Abbreviations: CI, confidence interval; TMD, temporomandibular disorders; WPT, widespread palpation tenderness; NA, not applicable; z, standardized z score, one unit change equals one standard deviation change.
Note: For all models, n=315 with participants who have complete information on all tested variables in the final model (i.e., Model 3).
Model 1: unadjusted logistic regression model
Model 2: adjusted for age
Model 3: adjusted for age and somatic symptoms (PILL)
