Table 4 Multivariable analysis taking the depression, anxiety and stress scores as dependent variables and the presence/absence of TMD 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
 Age -0.09 −0.26 < 0.001 − 0.12 − 0.05
 Bruxism at night (yes vs no*) 2.29 0.20 < 0.001 1.13 3.44
 Working hours per day 0.21 0.13 0.009 0.05 0.37
 Presence vs absence* of TMD 0.92 0.08 0.137 −0.29 2.12
Model 2: Linear regression taking anxiety (GAD-7 score) as the dependent variable.
Variable UB SB p 95% Confidence Interval
 Hours on phone per day 0.18 0.18 < 0.001 0.08 0.28
 Presence vs absence* of TMD 1.39 0.14 0.006 0.40 2.39
Model 3: Linear regression taking stress (BDS22 score) as the dependent variable.
Variable UB SB p 95% Confidence Interval
 Hours on phone per day 0.43 0.18 < 0.001 0.20 0.67
 Age −0.12 −0.17 0.001 −0.18 −0.05
