iPTH: intact parathyroid hormone, corrected calcium (mg/dL) = measured total calcium (mg/dL) + 0.8 (4.4- serum albumin (g/dL), where 4.4 represents the average albumin level; Analysis is based on XtGee: generalized estimating equation; *P value less than 0.05, was considered statistically significant.
