Both questionnaires were included, among others, in large comparative cross-national and cross-cultural studies [ 29, 30], and item response theory was applied to achieve cross-cultural comparability of work stress measurements [ 29].
Therefore, additional studies in large and comparable samples are necessary to further evaluate the factor structure of the US QoLISSY and the comparability of the measure across countries.
Numerous high-sensitivity CRP (hs-CRP) methods are available but their comparability in large populations has not been assessed.
An account of the percentage net primary productivity consumed by large herbivores should improve comparability, and aid future syntheses.
Another example of early cross-site integration is a study being performed by the ACC comparing prevalent ICD-9 codes across network sites for similar and different phenotypes to assess the comparability of large populations taken from different institutions.
Comparison of community-based survey data with surveillance data suggests only minor sampling biases in the former that – except for a few countries - do not seriously distort inter-country comparability, despite large variations in participation rates across countries.
The large dataset with comparable data across Europe, allowed us to study each gender separately and comparability of data between 34 European countries enabled us to give an overall view of determinants of PMH among people in Europe.
For samples containing N-glycans with a larger size distribution, however, comparability must be evaluated individually.
Anyhow, the main limitation of this study is the small preliminary patient collective which limits comparability to larger case serious in the literature.
Most of the cross-country analyses are facing the problem of cross-national comparability and a large variation in the economic, institutional and cultural context.
