Because the studies used different physical activity measures in their tests for trend (e.g., energy expended, intensity, frequency, or duration), as well as different categorisation schemes, we did not conduct a formal meta-analysis of trend across studies.
20 All the code lists we used, as well as the SMI categorisation, are available from http://www.clinicalcodes.org, 21 while more details on the Read code selection process in this SMI context have been provided elsewhere.
However, it is also known that prognostic markers based on IHC can provide inconsistent or contradictory results, owing to the use of different antibodies and processing methods (Atkins et al, 2004; Baker et al, 2005), as well as different scoring and categorisation systems.
There was a significant association with better tumour regression (P=0.041) as well as a post-treatment down-categorisation (P=0.040).
Validation in healthy individuals as well as those with affective disorders facilitated the categorisation of colors into positive, neutral and negative shades where it was found that the shade of a particular color, for instance light or dark, was just as important as the actual color itself in determining how an individual reacted to it.
The results have implications for the assessment of environmental effects through appropriate street categorisation in emission models, as well as the possible reduction of environmental effects through better traffic planning and management, driver education and car design.
But they insisted that the definition and categorisation of groups as jihadist, as well as the creation and execution of rules for counting and coding incidents, were guided by the "principles of transparency, clarity, and rigour".
Further categorisation relies on clinical and histological findings, as well as the detection of autoantibodies.
The risk categorisation of workers in this example included both scientific evidence as well as risk perception.
