Risk prediction for estrogen receptor-specific breast cancers in two large prospective cohorts

Background Few published breast cancer (BC) risk prediction models consider the heterogeneity of predictor variables between estrogen-receptor positive (ER+) and negative (ER-) tumors. Using data from two large cohorts, we examined whether modeling this heterogeneity could improve prediction. Methods We built two models, for ER+ (ModelER+) and ER- tumors (ModelER-), respectively, in 281,330 women (51%…

Reproductive factors, exogenous hormone use and risk of B-cell non-Hodgkin lymphoma in a cohort of women from the European Prospective Investigation into Cancer and Nutrition

The role of hormonal factors in lymphoid neoplasms etiology remains unclear. Previous studies have yielded conflicting results, been underpowered to assess many lymphoma subtypes, or lacked detailed information on relevant exposures. Within the European Prospective Investigation into Cancer and Nutrition cohort, we analyzed comprehensive data collected at baseline (1992–2000) on reproductive factors and exogenous hormone…

How are risk ratios reported in orthopaedic surgery journals? A descriptive study of formats used to report absolute risks

Purpose The numerical format in which risks are communicated can affect risk comprehension and perceptions of medical professionals. We investigated what numerical formats are used to report absolute risks in empirical articles, estimated the frequency of biasing formats and rated the quality of figures used to display the risks. Design Descriptive study of reporting practices.…
