Forest plot of mortality outcomes by subgroups. P, phosphorus; ALB, albumin; HR, hazard ratio. Bold indicates significance at p < 0.05. Cox regression results was from model 4 which was adjusted by age, gender, and history of diabetes and cardiovascular disease, serum levels of hemoglobin, high-sensitive C-reactive protein, intact parathyroid hormone, systolic blood pressure, diastolic blood pressure, total cholesterol, triglyceride, low-density lipoprotein cholesterol, residual renal function, and uses of phosphate binders, calcitriol, and α-ketoacid. HR > 1 indicates patients with phosphorus <1.5 mmol/L and albumin ≥35 g/L is more beneficial, and <1 indicates patients with phosphorus and albumin levels in the respective group is more beneficial.
