Results During study, 2,577 conducted, 162 (6%): 25 split titration (14%), 29 had syndromes (Down, Prader Willi, Wiedmann Beckmann, Achondroplasia), 4 tracheostomy studies, 6 infants < 12 months post intervention. Ninety-two included analysis. Median birth age was 31 weeks, interquartile range (IQR) 27-34 weeks. Thirty-two (34.8%) referred for 55 (59.8%) snoring; 18% index >5/hour, 14% fit criteria (RSD). There no statistically significant differences PSG parameters between RSD, remaining group, except lower obstructive apnea/hypopnea (Kruskal-Wallis ANOVA 8.621, p=0.0135) RSD group (median 0.7, IQR 0.3-0.9) than 1.7, 0.7-3.5), nonRSD/nonPLMS 2.0, 0.8-4.5).
