Cancer Epidemiol Biomarkers Prev 22:1612-9. 2013..The objective of this study was to estimate the probability of experiencing a false-positive after receiving annual FOBT screening for 10 years...
- Evaluating components of dental care utilization among adults with diabetes and matched controls via hurdle modelsMonica Chaudhari
Washington Dental Service, 9706 Fourth Avenue NE, Seattle, WA 98115, USA
BMC Oral Health 12:20. 2012..This project had two purposes: to develop a methodology to estimate dental care utilization using claims data and to use this methodology to compare utilization of dental care between adults with and without diabetes...
- A semiparametric censoring bias model for estimating the cumulative risk of a false-positive screening test under dependent censoringRebecca A Hubbard
Biostatistics Unit, Group Health Research Institute, Seattle, Washington 98101, USA
Biometrics 69:245-53. 2013..Models that provide accurate estimates under dependent censoring are critical for providing appropriate information for evaluating screening tests...
- Diagnostic imaging and biopsy pathways following abnormal screen-film and digital screening mammographyRebecca A Hubbard

Med Care 50:1053-9. 2012..Digital mammography is the dominant modality for breast cancer screening in the United States. No previous studies have investigated as to how introducing digital mammography affects downstream breast-related care...
- Modelling the cumulative risk of a false-positive screening testRebecca A Hubbard
Group Health Research Institute, Biostatistics Unit and Department of Biostatistics, University of Washington, Seattle, WA 98101, USA
Stat Methods Med Res 19:429-49. 2010..The estimated risk of an FP recall after 10 screening mammograms varied between 58% and 77% depending on the approach used, with an estimate of 63% based on what we feel are the most reasonable modelling assumptions...
- Cumulative probability of false-positive recall or biopsy recommendation after 10 years of screening mammography: a cohort studyRebecca A Hubbard
Group Health Cooperative and School of Public Health of the University of Washington, Seattle, USA
Ann Intern Med 155:481-92. 2011..False-positive mammography results are common. Biennial screening may decrease the cumulative probability of false-positive results across many years of repeated screening but could also delay cancer diagnosis...

Group Health Research Institute, Seattle, Washington
Cancer 119:3959-67. 2013..Biennial screening mammography retains most of the benefits of annual breast cancer screening with reduced harms. Whether screening guidelines based on race/ethnicity and age would be more effective than age-based guidelines is unknown...
