  1. e = exponential-e; Cr = Creatinine, urinary biomarker value needs to be normalised to urinary creatinine concentration before being entered in the equation.
  2. bVariable(s) needs to be range standardised before being entered into the equation, age to 120 yrs old, IL-5/Cr to 100 and ATP/Cr to 0.000001.
  3. Standard errors (SE) for constants and coefficients are reported in Table S4.
