Figure 2.

Percentage of inhibition of HAP dissolution by phytate, alendronate, and etidronate at 1 and 3 µM. Percentage of inhibition was calculated as it is indicated in the following formula “Percentage of inhibition = [mg calcium at 24 h for 0 µM–mg calcium at 24 h for 1 or 3 µM]/[mg calcium at 24 h for 0 µM] × 100”. Values are expressed as mean ± SE. Comparison were determined by ANOVA and Bonferroni as a post-hoc test. ^a p < 0.05 versus the value for the corresponding phytate concentration; ^b p < 0.05 versus the value for the corresponding alendronate concentration.
