Data are the median (interquartile range) or percentage. Characteristics measured at baseline (visits of reference or treatment). VDRA, vitamin D receptor activator.
a
Overall sets were divided into two groups on the basis of cinacalcet patterns at treatment visits.
b
Sets with oral VDRA in addition to intravenous VDRA.
