Patients’ mean activity during day vs. night in uncorrected and corrected data separately for diagnoses. The mean activity was significantly higher during the day (7 am–9 pm) than during the night (9 pm–7 am) in both uncorrected and corrected data in UWS and MCS/EMCS patients with stronger day-night effects in MCS/EMCS patients and uncorrected data. For better illustration, the data was log-transformed (right-hand y-axes); statistics were performed on the untransformed data (left-hand y-axes). Horizontal lines represent the medians, boxes the interquartile range (IQR; distance between the 1st [Q1] and 3rd quartile [Q3]), and whiskers extend at most to Q1−1.5*IQR (lower whisker) and Q3+1.5*IQR (upper whisker). Asterisks indicate significance: **p ≤ .01, *p ≤ .05. Abbreviations: MCS minimally conscious state, EMCS exit MCS, UWS unresponsive wakefulness syndrome
