However, our results indicated that FGF23 was not an independent risk factor for osteoporosis (Table 3), and it had no value in predicting osteoporosis in this study (data not shown), even though Mirza Ma and Lane Ne et al. demonstrated that serum FGF23 levels were related independently to fracture risk in elderly men with decreased estimated glomerular filtration (eGFR) [32, 33]. Here, FGF23 is linked to osteoporosis.
