Risk factors of patients with CKD associated pruritus.

Risk Factors	Characteristics
Inadequate dialysis	High level of BUN was a significant risk factor for severe uremic pruritus [9,10,11].
Hyperparathyroidism product	Hyperparathyroidism, the product due to the alteration of metabolism, can be involved in the pathogenesis and risk factor [12,13].
Elevated calcium x phosphorus product	Calcium and phosphate, the product due to the alteration of metabolism, can be involved in the pathogenesis and risk factor [9,14,15].
Xerosis	Xerosis is a common complication in HD patients and has an impact on the severity of itch [2,16,17].
Elevated serum magnesium and aluminum concentrations	Magnesium and aluminum, the product due to the alteration of metabolism, can be involved in the pathogenesis and risk factor [18,19,20].
