i The Children's Health Act (CHA) of 2000 established an earlier version of the IACC, but the CAA significantly changed the Committee by specifying membership requirements, mandating several activities and functions, and defining the Committee's role in facilitating public dialogue on matters related to ASD.
iiMore information on NIH autism spending can be found at the NIH RePORT Website.
iii Following the Children's Health Act of 2000, CDC's newly-established National Center on Birth Defects and Developmental Disabilities established the Autism and Developmental Disabilities Monitoring (ADDM) Network.
iv For the purpose of this report, publications concerning either environment or gene-environment interactions were considered as one category. The categorization algorithm was unable to discriminate accurately between these two related areas. Also, only a relatively small number of these publications specifically address gene by environment interactions (~20 publications in 2010). Please note that in the 2010 IACC ASD Portfolio Analysis Report, Environment and Gene-Environment are tracked separately, as these categories are distinguishable when applying a manual coding approach to research grant portfolios.
vi Description of funder types: 1) Government includes all public funding (i.e., State, Federal, etc.), 2) Private includes non-profit/philanthropic organizations as well as for-profit industry, 3) University includes all universities, public and private, 4) Hospital includes all hospitals, public and private, 5) Public/private partnership includes funding sources that have significant governmental and private support.
vii Funding acknowledgments to pharmaceutical companies in the ScienceWire™ database were manually reviewed to determine whether an acknowledgment indicated direct funding support or a general conflict of interest. Acknowledgments that were deemed conflict of interest statements were not included in this analysis.
viii Seven publications only acknowledged funding from hospitals and universities. These are included in the total number of publications with funding acknowledgments (870), but not represented in the Venn diagram.
ix For ease of analysis and figure clarity, all non-US funders, government and private, were grouped together for funding overlap analyses.
x This group represents a combination of non-US government and non-US private funders.
xi More information on NIH's Autism Centers of Excellence can be found in the Biennial Report of the NIH Director, 2008-2009.
xii More state by state details on US health-related Federal research funding provided by the NIH, the Centers for Disease Control and Prevention (CDC), and the Agency for Healthcare Research and Quality (AHRQ) can be found on the Research!America Website.
