Figure Lengend Snippet: Bland–Altman plots: Horizontal line drawn at the mean difference and at the mean difference plus and minus 1.96 times the standard deviation of the differences, with the y-axis reporting mean duration determine by polysomnography. a Polysomnography versus Actigraphy assessment of total sleep time. b Polysomnography versus Actigraphy assessment of wakeful states for the study cohort. Graphs c and d depict Polysomnography versus Actigraphy assessment of total sleep time amongst mechanically ventilated patients ( c ) and Polysomnography versus Actigraphy assessment of wakeful states for patients receiving mechanical ventilation ( d ). Non-ventilated patient total sleep time (PSG vs ACTG), and wake time (PSG vs ACTG) is represented in graph e and f
Article Snippet: ACTG data was analyzed as sleep or wake at 30-s epochs via the actigraphy analysis software (Actiware version 6.0.9; Phillips Respironics), using the predetermined activity count for each epoch within the software algorithm.
