Statistics are based on Cox proportional hazard analysis, and the hazard ratio is included to indicate effect size (HR: 1 = no effect; <1 = a reduction in the hazard; >1 = increase in the hazard).
¥95% confidence intervals for survival probability at 72 h post exposure.
∗Significantly decreased survival compared to the control at p < 0.05.
∗∗∗Significantly decreased survival compared to the control at p < 0.001.
