125313​

Indexed​

The measurement has been normalized by dividing it by​

an index value (such as Body Surface Area).​

125314​

The measurement is a change value expressed as a​

fractionofitsbaselinevalue.E.g.cardiacejectionfraction​

or fractional shortening.​

125315​

Calculated​

The measurement is calculated by incorporating one or​

more measured values into an equation other than a​

ratio, fractional change or indexed calculation.​
