- Reported statistics:
- Concentrations of trace elements in tissues were log transformed. Analysis of variance, t-tests, and Spearman's Rank Correlation tests were used to determine significant differences at P ≤ 0.05 unless otherwise noted. When F values indicated significant differences, Bonferroni's Multiple Pairwise comparison tests (Netter and Waserman 1974) were used to compare the geometric means for significant differences. Untransformed data were used for Spearman's Rank Correlation tests.
