HRs (and 95% CIs) for all-cause and cardiovascular mortality according to categories of intact PTH levels and history of PTx, using crude, case-mix-adjusted, and multivariable-adjusted Cox models. (a) All-cause mortality. (b) Cardiovascular mortality. The case-mix-adjusted analysis included the following variables: age, sex, duration of dialysis, and primary cause of renal failure. The multivariable-adjusted analysis included the case-mix variables plus BMI, history of CVD (myocardial infarction, cerebral infarction, cerebral hemorrhage, and amputation), Kt/V, nPCR, serum albumin, calcium, phosphorus, CRP, dialysate calcium, and use of VDRAs. *P<0.05. BMI, body mass index; CI, confidence interval; CRP, C-reactive protein; CVD, cardiovascular disease; HR, hazard ratio; Kt/V, dialysis adequacy; nPCR, normalized protein catabolic rate; PTH, parathyroid hormone; PTx, parathyroidectomy; R, reference; VDRA, vitamin D receptor activator.

(a) Intact PTH levels. (b) Serum calcium levels. (c) Serum phosphorus levels. PTH, parathyroid hormone; PTx, parathyroidectomy.
