  1. 1 = ((calculated value from the corresponding prediction equation-reference metabolic parameter/reference metabolic parameter)*100)
  2. 2 = Proximity to zero calculated as the difference between the reference metabolic parameter and the calculated value from the corresponding prediction equation (± 2 standard deviations) [13]
