Thanks for asking! Are you referring to the slightly earlier wake-up time? I just had a look at the net sleep time in the three groups, and got the following comparison:
Control: 8h 00m
0.15mg: 8h 02m
0.3mg: 7h 45m
But large p values as you can guess from the overlapping CIs.
(The seeming discrepancy between this data and wake-up time can be explained by the fact that wake-up time was the absolute time, whereas net sleep time is also affected by when I went to bed and how long it took me to fall asleep)
Yeah, the earlier wake-up time was what I was referring to. I’ve been interested for a while in whether melatonin reduces sleep duration, most studies use too much and find slight sleep lengthening. The 0.3mg decrease of 15 minutes is intriguing, begs for a replication attempt.
