  2. aOnly the significant variables in univariate logistic regression analysis are listed here
  3. bLogistic regression analysis with the forward stepwise method in model 1 was adjusted for all factors in the Table 1 except for sleep duration
  4. cResults in model 2 were derived from Model 1 with sleep duration added as another covariate
