Article Title: Validity of Actigraphy Compared to Polysomnography for Sleep Assessment in Children With Autism Spectrum Disorder
doi: 10.3389/fpsyt.2019.00551
Figure Lengend Snippet: Bland-Altman plots for the comparison of PSG and ACT for each sleep parameter. The mean of each sleep parameter with the two techniques is represented in the x -axis and differences (i.e., mean biases) for each sleep parameter between the two techniques are represented in the y -axis. Each subject is represented by a dot. The continuous line which passes through zero, representing perfect agreement between PSG and ACT, is the reference line. The bold dotted line represents the mean difference of the study sample (i.e., mean bias) for each sleep parameter with the two techniques. Differences are expressed as PSG—actigraphy, so a negative value indicates actigraphy overestimated the sleep parameter, whereas a positive value indicates actigraphy underestimated the sleep parameter. SL, sleep latency; WASO, wake after sleep onset; TST, total sleep time; SE, sleep efficiency.
Article Snippet: The aim of this study was to compare the agreement of actigraphy (MotionWare 8®—CamNtech MotionWare 1.1.20) with gold standard polysomnography in children diagnosed with ASD.
