Level of phosphate diets effect on fibroblast growth factor-23 levels in chronic kidney disease subjects: A meta-analysis.

Lower dietary phosphate levels had significantly lower 24-hour urinary phosphate excretion, intact fibroblast growth factor-23 level compared with higher dietary phosphate levels in chronic kidney disease subjects. This relationship forces us to recommend low dietary phosphate levels in chronic kidney disease subjects to decrease fibroblast growth factor-23 level to avoid any possible cardiovascular disease risk in such a subject.
