Legends of the figures
Figure 1: Scattergram of 30-minute and 10-minute risk scores according to the severity of obstructive sleep apnea syndrome over the second sleep cycle. The lines represent the medians. OAHI: Obstructive Apnea Hypopnea Index; OSAHS: Obstructive Sleep Apnea Hypopnea Syndrome; RS10: 10-minute Risk Score; RS30: 30-minute Risk-Score. OSAHS was defined as followed: absence if OAHI < 1.5, mild if OAHI between 1.5 (included) and 5 (not included), moderate if OAHI between 5 (included) and 10 (not included), and severe if OAHI ≥ 10.
Table 1: Point scoring method used for video analysis for calculating the 30-minute risk score (RS30). RS30 was calculated as the sum of the seven questions.
