![]() The sensitivity (S), specificity (E) and positive and negative likelihood ratio (LR+, LR-) for the different thresholds for RI or AHI were calculated 66 patients were included (47 men, mean age 51, median RDI 10.6, mean BMI 29.3 kg/m2). ApneaLink and SAHS were defined in three ways: AHI or respiratory disturbance index (RDI) >or= 5, 10 and 15 respectively. The ApneaLink software calculated: (1) risk indicator (RI)-a combination of apnea/hypopnea index (AHI) plus inspiratory flow limitation events and (2) the AHI. The two recordings were interpreted blindly. All participants (75) performed the ApneaLink and polysomnography (PSG) simultaneously in the sleep laboratory. ![]() The aim of this study was to evaluate the diagnostic accuracy of automated analysis of ApneaLink in patients with suspicion of SAHS. Portable sleep studies may play an important role to take decisions on patients referred for suspicion of Sleep Apnea-Hypopnea Syndrome (SAHS).
