LC50 — lethal concentration that kills 50% of the exposed flukes, LC90 — lethal concentration that kills 90% of the exposed flukes, LC99 — lethal concentration that kills 99% of the exposed flukes, UCL: upper confidence limit; LCL: lower confidence limit, SD: standard deviation. × ² — Chi-square; df: degree of freedom. Significant at p < 0.05 level.
