High Prevalence of Sleep Disturbance in Cirrhosis
Fig. 1. Examples of actigraphy of (A) a healthy control and (B) a cirrhotic patient with unsatisfactory sleep over three consecutive days. Each day is shown in one panel, with activity data in the upper trace. Based on the analysis of the activity data it is possible to estimate wake (upper horizontal line of the middle trace) and sleep (lower horizontal line of the middle trace) periods during the time spent in bed (horizontal line of the lower trace).
