No significant survival rate difference was observed between fish batches fed with experimental diets.
§Significant survival rate difference (by Mann Whitney rank sum test, p<0.05) between F32-ART5 and its sibling line F32-TEM.
The 5- and 10-year survival rate difference supports that PIPKIγ expression is inversely correlated to the survival of breast cancer patients.
This survival rate difference is due partially to a better response of oligodendroglioma to chemotherapy, including temozolomide or PCV- procarbazin, 1- 2-cloroethyl -3-cyclohexil-L-nitrosurea and vincristin [ 9– 1- 2-cloroethyl -3-cyclohexil-L-nitrosurea
In small mammals, the pattern also includes reduced reproductive output, higher survival rate, and differences in behaviour (see reviews in [ 9, 13]).
Furthermore, other analyses from the ICBP exploring stage and survival data for ovarian (Maringe et al, 2012) and breast cancer (Michel Coleman, personal communication), suggest that differences in access to treatments or tumour biology may also be having a role in differences in survival rates, although differences in staging procedures make comparisons difficult.
Since different clutches can show substantial differences in survival rate, presumably due to differences in egg quality from different zebrafish parents, paired within-clutch comparisons were used.
The Kaplan-Meier method was used to estimate cumulative survival rates, and differences in survival rates were assessed with the use of the log-rank test.
So while some are again ready to conclude that Bt corn poses no undue risk to the monarch, others say with such a minuscule survival rate, even important differences between the survival rates in the two fields would be tiny, probably requiring much larger-scale studies to detect.
