PTH and sarcopenia: Multiple regression analysis demonstrated that a higher log (iFGF23) was independently associated with greater handgrip strength (beta coefficient [β] = 5.39, 95% CI 2.07–8.72) and conferred a lower risk of sarcopenia (odds ratio (OR) = 0.14, 95% CI 0.02–0.75), after adjustment for age, gender, CCI, BMI, serum creatinine, calcium, phosphate, PTH, 25(OH)‐vitamin D, albumin, IS and CRP (Table 3).
