  • Univariate correlation calculated with: Spearman’s r where yes=1.

  • Multivariate correlation logistic multiple regression using stepwise forward technique using likelihood ratios to determine model. Multivariate model uses simplified predictor variables (EQ-5D score dichotomised about median), frailty low (vulnerable and above vs lower group of very fit to managing well), age per decade of years.

  • Excluded patients who chose transplant or MCM.

  • Values to two decimal places or three decimal places for p values.

  • eGFR, estimated glomerular filtration rate; HHD, home haemodialysis; MCM, maximum conservative management; PD, peritoneal dialysis; VAS, Visual Analogue Scale; WIMD, Welsh Index of Multiple Deprivation 2014.
