Correction

The original article [1] contains an error affecting the actigraphy time-stamps throughout the article, particularly in Table 1.

All data for this manuscript were collected in Liège, Belgium, and exported and analysed in London, Ontario. The authors have recently discovered that a software error occurred during data export that caused all actigraphy time-stamps to be shifted by exactly 6-hours due to the time-zone difference between Belgium and Ontario. As a result, the acrophase values reported in the original Table 1 should all be read as occurring 6-hours earlier in the day as displayed in the corrected Table 1 ahead (for example, if an acrophase is reported as 16:57 in Table 1, it should be read as 10:57). The corrected Table 1 appears as within this Erratum.

Importantly, as this software error added only a constant value to each time-stamp of each patient data set, no analyses or results are affected.
