Percent change in SIGH-SAD score as a function of net change in absolute deviation toward and away from PAD 6 in PM-melatonin treated advanced and delayed subjects. 13% has been added to the change in SIGH-SAD score to remove the average placebo response. Pretreatment vs. post-treatment shifts with respect to PAD 6 account for 35% of the variance. Adapted from [7], with permission.
