That statement, which some critics argue is too simple, is one of the major results of the paper, which includes a broad review of the literature and primary analysis of relevant data mainly from the National Science Foundation (NSF).
A more disease specific quality of life tool 22 would have been the ideal choice for primary measure, but relevant data were not available from the identified studies.
Additionally, though our initial search focused on updating systematic reviews, we nonetheless retrieved relevant primary studies to extract all relevant data, if they were not provided in the systematic reviews.
Second, the effects of the type of diabetes on the association between the polymorphism and DR were not addressed because the primary studies did not provide the relevant data.
Furthermore, the effect of low birth weight on childhood asthma in the identified studies was not the primary objective, possibly leading to missing relevant data that was not evident in the title or abstract.
This is not, however, to deny the importance of extracting and tabulating all relevant data from the primary studies: the tables remain an essential component of the process and are needed both to validate and to interpret the patterns revealed by the harvest plot.
The accuracy of diagnosis for primary OA was double-checked against the relevant data in the Finnish Arthroplasty Register.
The accuracy of the diagnosis of primary OA was double-checked against the relevant data in the Finnish Arthroplasty Register.
Another limitation, also linked to the impediments in the system for retrieving relevant data across levels of primary and secondary care, is the missed opportunity to link the hospital-based data to nursing home-based data.
Biological evolution is a complex concept that requires gathering relevant data, and teaching it in primary schools can be quite difficult.
