‡Due to small numbers of underweight patients (n=2), the underweight group was combined with the healthy weight group for this analysis.
§-Socioeconomic status was estimated using the Australian Bureau of Statistics data. Postcodes were coded according to the Index of Relative Social Disadvantage, a composite measure based on selected census variables, which include income, educational attainment and employment status.
eGFR, estimated glomerular filtration rate.
