FIG. 3.

Tumor fibrosis. (a) Extent of intratumor fibrosis and (b) extent of peritumor (capsular) fibrosis. While the change in the extent of intratumor or capsular fibrosis in the tumors from Japan as compared to the tumors from the fallout areas did not reach significance, the trend in both was that expected to be associated with a reduction in aggressiveness. In both (a) and (b), the England and Wales findings were intermediate between the Chernobyl and the Japanese cases. The whiskers are lines that extend from the box to the highest and lowest values, excluding outliers. A line across the box indicates the median. Filled circles represent extremes (cases that are beyond 3 box lengths from the upper or lower end of the box).
