  • BMI, body mass index; GCSE, General Certificate of Secondary Education; NVQ, National Vocational Qualification.

  • a Derived using multivariable logistic regression and multiple imputation; 20 imputed datasets were modeled separately and then combined to produce final parameter estimates.

  • b Missing data were imputed for BMI (n=243), comorbidity (n=30), time since first seen by a nephrologist (n=24), and socioeconomic variables (n=146).
