On a multivariate analysis, older age (adjusted hazard ratio (aHR) 1.06 (1.03–1.09), p < 0.001), cardiovascular disease (aHR 2.21 (1.21–4.04), p = 0.010), CVC at start of HD (aHR 3.09 (1.58-6.03), p < 0.001), lower PTH (aHR 0.998 (0.997–1.000), p = 0.014) and higher CAR (aHR 1.13 (1.02–1.24), p = 0.015) were independent predictors of early mortality. Here, PTH is linked to cardiovascular disorder.
