## Figure 8.
Abdominal pain: SROC for cancer. SROC = Summary ROC. 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 diagonal line joining (0,0) and (1,1) represents an ROC of no diagnostic
value.
