This paper describes a pure numerical methodology (FE database) to improve the representativeness of joint equivalent models for airframe crashworthiness.
While the restriction of our search to MEDLINE database could have affected the representativeness of systematic reviews, we believe the included reviews represent those typically accessed by clinicians.
Considering the general objective of the analysis and the sampling methodology of Italian FADN database, which ensures a statistical representativeness at regional level (Abitabile and Scardera 2008), the correspondence between the sample and the universe is only evaluated in a qualitative way.
The representativeness of the database enhances the generalizability of study results.
However, there is some variability in the intensity of surveillance both spatially and among species, which influences the representativeness of the database.
Due to possible miss-assignments caused either by the representativeness of the database or to the amelioration of the transferred sequences [ 93], only broad categories of donors are presented.
To validate the representativeness of this database for meningitis epidemiology after NmA elimination, we compared the distribution of annual incidences between health areas before and after PsA-TT introduction.
To ensure the representativeness, the research database of LHID2000 contains all the original claims data of a total of 1,000,000 individuals who were randomly sampled from the 23 million beneficiaries enrolled between 1996 and 2000 in the National Health Insurance (NHI) programme [ 11].
Although there is no guarantee that searching a wider range of databases increases the percentage of relevant papers identified, failing to consider the breadth and geographical representativeness of the databases selected raises concerns about evidence that could have been missed.
This representativeness of the databases, and the lack of recall, selection and respondent biases, also makes the results more generalisable.
