Figure 5: Circadian Rest-Activity Relative Amplitude Correlated to DLMO.
Comparing the timing of dim light melatonin onset (DLMO) to circadian rest-activity rhythms by wrist actigraphy there was a significant circular to circular correlation in A) Day Workers (DW) pre alcohol and B) DW post alcohol. In Night Workers (NW), C) and D) RA did not correlate with DLMO. In Alcohol use disorder (AD) E) there was a less robust but significant correlation between DLMO and RA.
