Crossover analysis of differentially altered metabolites between the three groups after calcium supplementation in rats. A The Venn diagram clearly shows the similarities and differences in differentially altered metabolites among the three groups, with 46 differentially altered metabolites shared among the three groups. B Heatmap analysis of the differentially altered metabolites showing that 6 differentially altered metabolites were downregulated significantly and 40 differentially altered metabolites were upregulated significantly
