[…] Data were expressed as means ± SD or number (n; %). Cronbach’s alpha coefficient was calculated and used to measure the internal consistency of the Arabic version of the SBQ. Intraclass correlation coefficients together with either Pearson’s correlation coefficients or Spearman’s rank-order coefficients were used to evaluate the test-retest reliability. Cronbach’s alpha coefficient was used to measure the internal consistency of the Arabic SBQ. Coefficients with values > 0.7 were considered acceptable. The receiver-operating characteristic (ROC) curves between the SBQ scores and the PSG AHI scores were assessed at AHI cut-off values of 5, 15 and 30. To assess the extent of the rise of the ROC curve to the upper left-hand corner, the area under the curve (AUC) was measured. In general, a steeper rise of the curve corresponded with better test results. An area of 1 represents perfect agreement, and an area of 0.5 represents the lowest possible agreement. In this study, we adopted the classification of AUC values used by Erman et al.; in this classification, 0.9 to 1 is considered excellent, 0.8 to 0.9 is considered very good, and 0.7 to 0.8 is considered good []. The sensitivity and specificity of the test, positive predictive values (PPV), negative predictive values (NPV) and positive and negative likelihood ratios (LR) were calculated for the same cut-off values of the AHI. In general, a likelihood ratio of < 1 indicates that the test result is associated with the absence of disease, whereas a likelihood ratio > 1 indicates that the test result is associated with the presence of disease. Likelihood ratios below 0.1 and above 10 are considered to provide strong evidence to rule out or rule in diagnoses, respectively. Values of p < 0.05 were considered statistically significant. Standard statistical software (IBM SPSS, version 21.0, Armonk, New York, USA) and Systat SigmaPlot, version 13, San Jose, CA, USA) were used for data management and analysis. […]
