Adjusted PD for decrease in iPTH levels according to increased VDRA, starting cinacalcet, and their combination. Reference, increased VDRA, starting cinacalcet, and combination were defined by patterns of not starting cinacalcet and not increased VDRA, not starting cinacalcet and increased VDRA, starting cinacalcet and not increased VDRA, and starting cinacalcet and increased VDRA, respectively. We estimated adjusted PDs for decrease in iPTH compared with the reference group, using generalized estimating equation models. PD, proportion difference; iPTH, intact parathyroid hormone; VDRA, vitamin D receptor activator.
