Table 5 Multivariable analysis taking the depression, anxiety and stress scores as dependent variables and the TMDseverity score as an independent variable

From: Prevalence of temporomandibular joint disorder in the Lebanese population, and its association with depression, anxiety, and stress

Model 1: Linear regression taking depression (PHQ-9 score) as the dependent variable.
Variable UB SB p 95% Confidence Interval
 TMD severity (FAI score) 0.10 0.40 < 0.001 0.08 0.13
 Age -0.06 −0.18 < 0.001 −0.09 − 0.03
 Working hours per day 0.17 0.10 0.028 0.02 0.31
 Bruxism at night (yes vs no*) 1.12 0.10 0.046 0.02 2.22
Model 2: Linear regression taking anxiety (GAD-7 score) as the dependent variable.
Variable UB SB p 95% Confidence Interval
 TMD severity (FAI score) 0.10 0.45 < 0.001 0.08 0.12
 Hours on phone per day 0.13 0.13 0.005 0.04 0.22
Model 3: Linear regression taking stress (BDS22 score) as the dependent variable.
Variable UB SB p 95% Confidence Interval
 TMD severity (FAI score) 0.23 0.42 < 0.001 0.18 0.28
 Hours on phone per day 0.37 0.15 < 0.001 0.15 0.58
 Age −0.07 −0.10 0.031 −0.13 − 0.01
