Abbreviations: CI, confidence interval; HR, hazard ratio.
a
Age was treated as a continuous variable for Cox regression analysis
b
Comorbid conditions include: attributed cause of end stage renal disease, body mass index, hypertension, diabetes, chronic obstructive pulmonary disease, tobacco, cancer and congestive heart failure
Multiple imputation handled missing data within Model 4 for missing body mass index data (2.36%). Observations with missing values were excluded from the descriptive statistics for each variable.
