Associations were estimated using multiple logistic regression analyses [P value, odds ratio (OR) and 95% CI]. For each independent variable that was removed during the backward elimination procedure, the P-to-exit value is reported.n/a, not applicable (based on the outcome of the single regression analysis, this variable was not selected for inclusion in the multiple regression); TMJ, temporomandibular joint.
