The results of WNN compared with results of international reference ionosphere 2012 IRI-20122) and international GNSS service (IGS) products.
Comparison was made with the international reference levels as well as with the 5th percentile for the study group.
The assay was calibrated with the international reference preparation (87/650, National Institute of Biological Standards and Controls, Potters Bar, Herts, UK) and was used at detection limits of 20 pg ml−1 plasma.
For the primary analysis, osteoporosis status was indicated by either femur neck BMD < 0.56 g/cm or total hip BMD < 0.64 g/cm, per the osteoporosis cutoffs reported in the NHANES III femoral bone density study conducted by Looker et al.

The potency of the in-house reference serum (identical for both sites) was assayed in parallel with the second International Reference Reagent for live attenuated poliovirus (NIBSC #66/202) so that the results could be converted to International Units (IU).
Compared with the international references for absolute laser power measurements, our cavity can be considered as a good absorbing cavity [3, 13 15].Our cryogenic radiometer is an electrical substitution detector operating at liquid nitrogen temperature (77 K).
That became an international reference point with which I could very easily be pigeonholed.
One of each of the kilogram and metre prototypes were chosen by lot to serve as the definitive international reference piece with the remainder being distributed to signatories of the Metre Convention.
