Distribution of odds ratios for events preceding the onset of dysthymia and major depressive disorder.

<p>The vertical axis shows the odds ratios, the horizontal axis the sixteen stressful life events that precede the onset of MDD alone (shown as a red box plot) and dysthymia with MDD (blue boxes). Box plots show the distribution of comparisons with 100 simulated ages of onset. Note that the result for the rape event on MDD alone is not shown because the OR is 40.
