The figure shows risk estimates on a logarithmic scale for breast cancer in users of DMPA (Depo-Provera) over a variety of studies conducted from 1987 to 2012. The odds ratios and 95% confidence intervals from Lee et al. (1987), Paul et al. (1989), the World Health Organization (WHO) in 1991, Shapiro et al. (2000), and Li et al. (2012) are displayed. The odds ratios presented are higher than 1, indicating an increased risk of breast cancer with DMPA use for all subjects and those using DMPA for 12 months or longer.*
