Table 2.

Table of survival probabilities by treatment level. The probabilities, along with their related 95% confidence interval limits, were calculated using the normal approximation.

A	1000	0.116	0.056	0.226
	1200	0.046	0.014	0.140
	1400	0.020	0.004	0.098
B	1000	0.055	0.021	0.137
	1200	0.013	0.003	0.066
	1400	0.004	0.000	0.039
C	1000	0.049	0.022	0.106
