nmol/l cortisol (IA)
nmol/l cortisol (factor score)
Decimal separators are defined as dots (.) The use of other separators will result in Not-A-Number (NaN) error messages.
Comparison of IAs is only indirectly feasible via cortisol factor scores and only valid upon comparability of IA revisions (see Miller et al., 2011).
Inverse conversion functions are estimated: All interpolation polynomials yield a coefficient of determination (R^2) > .99.
