Am J Epidemiol 153:394-403. 2001..3 times larger study than would be estimated by the standard approach. The implications of the results for the ability of FFQ-based epidemiologic studies to detect important diet-disease associations are discussed...
- Checking for completeness of 24-h urine collection using para-amino benzoic acid not necessary in the Observing Protein and Energy Nutrition studyA F Subar
Division of Cancer Control and Population Sciences, US National Cancer Institute, Bethesda, MD 20892 7344, USA
Eur J Clin Nutr 67:863-7. 2013..The purpose was to examine the effect of including urine collections deemed incomplete based on PABAcheck in a dietary measurement error study...
- Evaluation of 2 brief instruments and a food-frequency questionnaire to estimate daily number of servings of fruit and vegetablesF E Thompson
National Cancer Institute, Bethesda, MD, 20892 7344, USA
Am J Clin Nutr 71:1503-10. 2000..Measurement of fruit and vegetable intake is important in the surveillance of populations and in epidemiologic studies that examine the relations between diet and disease. Some situations require the use of brief dietary assessment tools...
- Evaluation of alternative approaches to assign nutrient values to food groups in food frequency questionnairesA F Subar
National Cancer Institute, Bethesda, MD 20892 7344, USA
Am J Epidemiol 152:279-86. 2000..Mean methods for assigning nutrients to food groups were superior to median approaches for all measurements. Among the mean methods, no single variation was consistently better...

National Cancer Institute, Bethesda, MD 20892 7232, USA
Am J Epidemiol 154:1119-25. 2001..The large size and wide intake range of the cohort will provide ample power for examining a number of important diet and cancer hypotheses...
- Comparative validation of the Block, Willett, and National Cancer Institute food frequency questionnaires : the Eating at America's Table StudyA F Subar
Applied Research Program, Division of Cancer Control and Population Sciences, National Cancer Institute, Bethesda, MD, USA
Am J Epidemiol 154:1089-99. 2001..These data show that the DHQ and the Block FFQ are better at estimating absolute intakes than is the Willett FFQ but that, after energy adjustment, all three are more comparable for purposes of assessing diet-disease risk...
