Table 3. Logistic regression model showing predicting factors of TMDs in COVID-19 infection (N = 116).
In the backward elimination logistic regression to predict temporomandibular disorders (TMDs) in COVID-19 infection, variables entered in step 1 were age groups, stress level during the infection, fever episodes during the infection, gastro-esophageal reflux during the infection, toothache during the infection, and having vitamin D deficiency. Nagelkerke R-square = 0.275; Hosmer-Lemeshow: p = 0.994; *P < 0.05; †aOR = adjusted odds ratio; ‡95% CI = 95% confidence interval

| Gastro-esophageal reflux during the infection | No (reference) | - | - | |
