T -test results show that the concentrations of Ba, Na, P, and Sr have statistically significant differences between the two egg groups ( p < 0.05), among which P shows a highly significant difference ( p < 0.01), Sr shows an extremely significant difference ( p < 0.001), while Mg shows no statistically significant difference ( p > 0.05) ( Table S2 ).
