A number of additional sources were searched to identify studies in progress, unpublished research or grey literature: Conference Proceedings Citation Index Science and Social Science, OAIster, ClinicalTrials.gov, Health Services Research Projects in Progress (HSRProj) and the Trip database.
These findings highlight the need for additional research to identify sources and pathways of human exposure to BPA and to evaluate potential health effects that may result from human exposures to BPA.
Nevertheless, our findings highlight the need for additional research to identify the sources and routes of exposure to BPA, especially in children, and the need for epidemiologic studies to target health outcomes related to BPA exposures in children.
More important, this example highlights the need for additional research to identify all sources and pathways of human exposure to these chemicals, particularly for those used extensively and suspected to affect human health.
These NHANES data suggest that the U.S. general population is often exposed to DIDP and DINP and highlights the need for additional studies to identify potential sources of DINP and DIDP.
One additional source of feedback to identify students' attitudes and professionalism is to seek input from the clerkship coordinator and all of the non-physician staff with whom the students interact during the clerkship-clerks, techs, nurses, etc.
In addition to the data collected by the consultants, data from a variety of additional sources were identified and added to the data set.
References listed in published articles such as literature reviews were screened to identify additional sources not identified in the database searches.> -wrap-foot> *Treased as a placeholder for any unknown term(s) Only papers published in Chinese or English were included in the study.
