A -- STATISTICAL SUPPORT FOR NIEHS STUDIES SOL N/A (See Item 17) POC Thomas M. Hardee, Contracting Officer (919) 541-0429 WEB: None, None. E-MAIL: None, None. The National Institute of Environmental Health Sciences intends to negotiate with Analytical Sciences, Inc. of Durham, NC on a sole source basis to expand the computational efforts described under paragraph h. of the Statement of Work of existing contract N01-ES-65401. Specifically, the expanded effort will consist of producing data sets and documentation on analyses already underway or anticipated in the near future, for example, analysis of serum organochlorine levels in relation to childhood outcomes using the Collaborative Perinatal Project Data Set, analysis of serum organochlorine levels in relation to risk of breast cancer, analysis of phenolphtalein-continuing laxative use in relation to risk of ovarian cancer, analysis of factors associated with elevated levels of follicle stimulating hormone and luteinizing hormone in premenopausal women using NHANES III data, and analysis of tubal ligation in relation to menstrual cycle patterns in a cross-sectional study of 300 premenopausal women aged 38 to 49. Authority: 41 U.S.C. 253(c)(1) as set forth in FAR 6.302-1 and HHSAR 306.302-1. Inherent duplication of costs to the Government and unacceptable delays impacting upon the specific studies to be conducted make competition unfeasible. See numbered Note 22.
