Figure 3. Comparison of the errors made by method 1 (STOP-BANG) and method 2 (logistic regression model).

(A) Visualization plot of individuals in the actual group (ie, no/mild OSA group and moderate/severe OSA group) and the estimated group screened using method 1 and method 2. Red indicates the moderate/severe OSA group and green indicates the no/mild OSA group. (B) Contingency table for the McNemar test. AHI = apnea-hypopnea index, OSA = obstructive sleep apnea, SBQ = STOP-BANG questionnaire.
