One‐way ANOVA analysis to test the difference in fluoro‐ruby uptake between each Cd dose in either females or males. In both sexes, fluoro‐ruby uptake was decreased when the Cd concentration was 2 ppm. The Brown–Forsythe and Welch ANOVA tests were used because the SDs were not the same in each Cd dose. Tamhane’s multiple comparisons test was used to compute individual variances for each comparison. Difference between columns (Mean Diff.), 95% Confidence Interval of difference (95% CI of diff.) Not significant (ns), * for < 0.05, ** for < 0.01, *** for < 0.001, **** for < 0.0001.
