Relative risk of death resulting from coronary artery disease for patients with serum PO4 > 6.5 mg/dl (versus 2.4 to 6.5 mg/dl): Sensitivity analyses (n = 12,687)

Covariate Adjustments Relative Risk P
Main model (age and duration of ESRD at study start, race, gender, diabetes, AIDS, neoplasm, active smoking) 1.41 <0.0005
Main model + skipping ≥1 session/mo 1.41 <0.0005
Main model + dose of dialysis (Kt/V) 1.41 <0.0005
Main model + anemia (hematocrit) 1.42 <0.0005
Main model + nutritional indices (BMI, creatinine, albumin) 1.39 <0.0005
Main model + atherosclerotic disease (coronary, cerebral, and peripheral) 1.51 <0.0005
All of the above factors combined 1.36 <0.01
