## Figure 2.
Bleeding: cancer and polyp comparison. crc = colorectal cancer. The horizontal and vertical dimensions of the each ellipse
are proportional to the square root of the number of non-diseased and diseased respectively.
+ shows the expected sensitivity and 1-specificity for the curve. The paired points
(one black and one open joined by a dotted line) represent a within study comparison.
The diagonal line joining (0,0) and (1,1) represents an ROC of no diagnostic value.
