This is a line graph. The horizontal axis shows the Allocation ratio, labeled 1, 2, 3, 4, 5. The vertical axis shows the Effect size detectable, labeled 0, 0.1, 0.2, 0.3, 0.4. A single line starts at allocation ratio = 1, effect size = 0.205, and rise slowly and then more steeply to allocation ratio = 5, effect size = 0.275.
