Multiple regression models for serum phosphate (mg/dl) in CKD male patients: Total testosterone

Unadjusted (β, P) (r2 = 0.12)Model 1 (β, P) (r2 = 0.46)Model 2 (β, P) (r2 = 0.63)
Total testosterone (nmol/L)−0.35 (<0.001)−0.10 (0.04)−0.03 (0.54)
Age (years)0.01 (0.88)0.02 (0.59)
eGFR (ml/min per 1.73 m2)−0.52 (<0.001)−0.15 (0.07)
Serum calcium (mg/dl)−0.17 (0.005)−0.22 (<0.001)
PTH (pg/ml)0.79 (<0.001)
  • CKD, chronic kidney disease; eGFR, estimated glomerular filtration rate; PTH, parathyroid hormone.
