Statistical analysis of individual factors predicting sleep bruxism.(A) Receiver operating characteristic curve with bruxism as the outcome variable. Comparison of (B) age, (C) CMI, (D) cortisol, and (E) PSQI global scores, which are key parameters distinguishing between the TMD_nonbruxer and TMD_bruxer groups. For A, the results were obtained using the ROC analysis. Results for B, C, D, and E were analyzed using t-tests. TMD temporomandibular disorder, CMI craniomandibular index, PSQI Score pittsburgh sleep quality index global score, ACTH adrenocorticotropic hormone; cortisol/ACTH ratio, DEP depression, ANX anxiety. To obtain significant results, the two-tailed level of statistical significance of the p-value was set at p < 0.05. *p-value < 0.05, **p-value < 0.01, ***p-value < 0.001.
