Statistical P values are given in italics

The results are given for 100% dose, 50%, 25%, and 12.5% of full dose. These results were obtained from 163 subjects. Post hoc ANOVA with correction for multiple comparisons indicates statistically significant differences between 12.5% dose and 100% dose in segments #4, #5, and #6, but not other segments
