Length of time awake has no effect on my sleepwalking

As part of my investigation of what factor impacts my sleepwalking, I looked at the effect of the amount of time spent awake that day. This is based on studies showing that sleep deprivation could be a triggering factor for sleepwalking.

The amount of time being awake (my daytime length) does not correlate with any of my sleepwalking scores, as the graphs below show.

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.
