Cox model 1 was adjusted for age at ESRD onset, sex, race, history of diabetes, hemoglobin, GFR, Serum albumin, geographic location, median income, and duration of pre-ESRD nephrology care.
Cox model 2 was adjusted for BMI and Comorbidity index in addition to the covariates listed above in model 1.
Note: P value was <0.001 for all the above variables in both the models except i) for diabetes variable for the outcome transplant for those who got listed in the 2nd model (P=0.42), ii) missing category in hemoglobin for the outcome listed/ transplanted without being listed (P=0.12 and 0.18 for model 1 and 2 respectively), and iii) for urban category in geography for the outcome listed/ transplanted without being listed (P=0.22 and 0.002 for model 1 & 2 respectively)
