Statistical analysis | |
Statistical methods |
Shapiro–Wilk normality test and Bartlett's test for homogeneity of variance and one way analysis of variance, followed by Dunnett's multiple comparison test or if unequal variances were observed. Kruskal–Wallis non‐parametric analysis of variance; and a subsequent pairwise analysis of control values against treated values using the Mann–Whitney ‘U' test, where significance was seen. |
Results | |
Findings reported by the study author/s |
No treatment‐related findings. Absent renal papilla was noted in one fetus in the intermediate dose and in two foetuses (from different litters) in the high‐dose group. These findings are reported to be within the range of historical controls. |
No observed adverse effect level, lowest observed adverse effect level, benchmark dose/benchmark dose lower bound | The no observed adverse effect level’ (NOAEL) for the pregnant female and for prenatal developmental toxicity was considered to be 15,000 mg/kg diet equal to 1,228 mg/kg bw per day. |
Further information | |
Panel assessment: The Panel considered that the test substance did not adversely affect pregnancy or in utero development up to an oral dose of 1,228 mg/kg bw per day. |
