Fig. 10From: Metabolomics and physiological analysis of the effect of calcium supplements on reducing bone loss in ovariectomized rats by increasing estradiol levelsCorrelations between calcium and estradiol levels with 46 differentially altered metabolites. The correlation coefficients of 10 of 46 metabolites with calcium were greater than 0.6, with the blue circles and positive values indicating a significant positive correlation and the red circles and negative values indicating a significant negative correlationBack to article page
