Notes. Adjusted p-values are Family-Wise Error Rate p-values adjusted for multiple comparisons to control for Type I error using the Holms’ method; multiple testing were done separately for non-linearity and interaction tests. No test was conducted for personal-social because SCU was the only metal with a significant main effect.
