While this is the biggest change to the USB format since it was standardised in 1996, it's by no means the first.
A wavelength of 1550 nm is deemed suitable as it is standardised for telecoms use, maximises transmittivity in the fibre and is not readily absorbed by the atmosphere.
It is standardised to have a standard deviation of 1 across fields and countries, so that a value of 1 (−1) indicates that the saturation is one standard deviation above (below) the average observed across all fields and countries.8.8
This approach not only takes CIECAM into practical application for the first time since it was standardised in 1998, but also introduces a new way of segmenting traffic signs in order to improve the accuracy of colour-based approach.
That lesson had a strong logistical component as well: The small size of many North American bathrooms made it difficult to accommodate both a regular toilet and a bidet, and plumbing in homes wasn't a simple thing to change once it was standardised for the non-bidet flush toilet.
Since AIX% varies with heart rate in an individual, it was standardised to 75 beats per minute.
An INR is not an appropriate test in massive haemorrhage because it is standardised for warfarin control, and results may be misleading in the context of dilutional and consumptive coagulopathies and liver disease.
As animal handling has been found to have a considerable impact on FDG-PET results, it was standardised for all animals (Lee et al, 2005; Fueger et al, 2006).
The intervention in ETIC is novel because it is standardised with the topics generally used (clinical alarm signs, physical activity, diet and cardiovascular risk factors) [ 35], but it also involves a holistic approach, centred on the patients' needs and feelings and taking into consideration their comorbidities and the representations of their disease [ 36].
Dividing the absolute difference by the placebo mean change from baseline results in an effect size that represents the percentage reduction in the placebo decline - an effect size >100% indicates an improvement over baseline: This effect size has the advantage that it is standardised to time rather than to the variability of a group of patients.
