Abbreviations: AIC = Akaike information criterion; AUC = area under the ROC curve; BIC = Bayesian information criterion; d = daytime; dn-NAP = number of daytime naps; D-PSG = daytime polysomnography; ICSD = International Classification of Sleep Disorder; MSLT = multiple sleep latency test; ROC = receiver operating characteristic; SOREMP = sleep-onset REM period; TST = total sleep time.
“Correctly classified patients (%),” AUC with 95% CI (%), AIC and BIC in the predictive logistic models using the D-PSG markers (individually and in combination) for group 1, MSLT-ICSD and MSLT-neurology criteria14 as independent variables, and the reference standard as dependent variable for the whole data set.
