  1. The results were obtained from χ2 test with Bonferroni adjusted post hoc analysis and the mean difference between groups was obtained by ANOVA with Tukey’s post-hoc test. p-Value significance was set at <0.05. *: p-value <0.05, **: p-value <0.01. TMD: temporomandibular disorder, VAS: visual analogue scale, SD: standard deviation, ESS: Epworth sleepiness scale, 1 in Post-hoc test: the mean value of myalgia group, 2 in Post-hoc test: the mean value of arthralgia group, 3 in Post-hoc test: the mean value of mixed TMD pain group.
