↵‡ interaction of potassium and albumin. Other variables included in the model were current age, serum urea, serum creatinine, serum phosphate, gender, age at start of dialysis, frequency of dialysis weekly, incidence-hepatitis, hospital-acquired hepatitis, dialysis duration in months, causes of dialysis and comorbidities
