However, as key items for risk of bias assessment were rated unclear because of lacking information regarding representativeness and response rate, the reported results had to be considered with caution.
For more information on the representativeness and quality of these data, please contact ICNARC.
Information about the representativeness of markers is directly available for sequenced genomes.
The system is continuously being improved, and additional information on the representativeness of EARSS data is being collected.
However, information regarding the representativeness of these clinical populations is limited, and thus the generalizability of research findings is uncertain.
The high similarity between empirical and simulated data is a first result for the validation procedure, giving important information about the representativeness of the model.
However, current information regarding the representativeness of clinical populations from these integrated health care delivery systems is limited, and thus the generalizability of research findings to the overall population is uncertain, particularly in cancer control research.
In addition, a severity and frequency rating by the parents is collected based on observations during the previous week, and information reporting on the representativeness of this rating.
First, all studies should include information on response rates, representativeness of the sampling frame (calendar year, region, population sampled, etc)., valid quality assurance measures, and adequate statistical power to address the question(s) of interest.
Expectations for well-designed self-administered surveys are high[ 1] and results can only be drawn and generalized based on the quantity, quality and representativeness of information returned[ 2].
