The underreporting of cost perspective in cost-analysis research: A systematic review of the plastic surgery literature.

Background: Cost-analysis research can influence healthcare policies and practices. There is inherent bias depending on the chosen cost perspective (hospital, third-party payer, societal), and conclusions can change based on the perspective used. These perspectives may or may not be well declared or justified when performing cost-analysis research.

Education and risk of cancer in a large cohort of men and women in the United States.

Background: Education inequalities in cancer incidence have long been noted. It is not clear, however, whether such inequalities persist in the United States, especially for less common malignancies and after adjustment for individual risk factors.

Methodology/principal Findings: Within the NIH-AARP Diet and Health Study, we examined the association between education and the risk of developing cancers in a prospective cohort of 498,455 participants who were 50-71 year old and without cancer at enrollment in 1995/96.
