The 2:1 ratio is certainly more commonly used. But, it is my understanding
that this ratio is based on an assumption that males are less likely to seek
treatment for depression. I don't place much trust in data manipulation
techniques, and chose instead an estimate based on actual reported
incidences of major depression. However, I am no statistician and there may
be more to the 2:1 ratio than I am aware. I have no problem conceding to the
2:1 ratio; it has no major impact on my arguments.
