aspirin: Aspirin use and breast cancer risk

aspirinR Documentation

Aspirin use and breast cancer risk

Description

This data set can be used to examine the recent epidemiological studies on aspirin use and breast cancer risk published from 2001 to 2007 within a meta-analysis, and to investigate reasons for heterogeneity between the individual studies.

We systematically searched for cohort-studies and case-control-studies from 2001-2007, which evaluated the association between aspirin and breast cancer risk. A total of 15 studies (seven cohort studies and eight case-control studies) met the inclusion criteria.
