3. Figure 1
Apoptotic cells per section (plotted on a log scale) versus activity grade. (solid line, ■) Scale comprises grades 1, 2, 3, and 4. (dotted line, ◆) Scale comprises grades 1, 2A, 2B, 3, and 4. The former 2 is divided into low (2A) and high (2B). This shows the grading scale with 2A and 2B with more equally spaced ratios, appearing as more of a straight line on the log plot.
