Multivariable OSA prediction (MOP) model
As shown in Table 2 , reported loud snoring, dry mouth in the morning and being overweight were the questions on the SRBD we found to associate with OSA in univariable logistic regression. In multivariable logistic regression, all three predictors remained significantly associated with OSA (Table 3 ). OSA probability was calculated for each participant with the beta coefficients of the logistic regression equation (Figure 2 ).
