Notes: a total vascular calcification score per 1 point score increase; b vascular calcification present compared to absent in either artery; c vascular calcification present in abdominal radiograph, in both abdominal and pelvic radiographs, and in all radiograph (abdominal, pelvic, forearm and hand radiographs) compared to participants without any vascular calcifications in all radiographs.
Model 1: adjusted for age and gender.
Model 2: adjusted for age, CAD, hypertension, diabetes and hyperlipidemia.
Model 3: adjusted for age, phosphorus level, Kt/V, albumin level, PTH level and duration of dialysis.
Model 4: adjusted for age, diabetes, phosphorus level, albumin level, hypertension, Kt/V and pulse pressure.
