I would love a well-researched list like that. My personal prioritized list is: therapy, medication, close friendships, meditation, journalling, reading books on psychology, getting enough sleep, exercise. (I guess that's ordered from most to least promising, not necessarily order of things to try.) But it's mostly just intuition from my own experiences, not scientific. My gut reaction is that sleep deprivation is worth trying, but probably near the bottom of the list. I've found that sleep deprivation has a strong correlation with depression for me. But different things work for different people.
