Mean is over all dialysis patients including those with Medicare as secondary payer.",, ,, 3Coefficients of variables with unconstrained coefficients less than 0 were constrained to equal 0.,, 4Coefficients of variables with coefficients with t-statistics < 1.0 were constrained to equal 0.,, 5Coefficient was constrained to equal coefficient from the CMS-HCC Aged-Disabled Community Model (2002-2003 Calibration).,, "6The interaction DM_CHF_RF (where RF = renal failure) is the same in this population as DM_CHF because all sample members have renal failure. Hence, this three-way interaction is not included.",, 7These coefficients are set to zero because beneficiaries on whom the model is calibrated have renal failure and are in dialysis status.,,
