Ubiquinol does not affect my sleepwalking

As part of my investigation of what factor impacts my sleepwalking, I looked at the effect of ubiquinol because of the vague link between antioxidants and sleep benefits. 

Ubiquinol has no effect on my sleepwalking, as shown on the graphs below. Some trends are visible but none are statistically significant.

Average values, +/- SEM. % variation and statistical significance are indicated (if less than 1%)

Data exclude nights with clonazepam and are normalized for the effect of coffee and tiredness.
