Data are from the Medical Expenditure Panel Survey (MEPS) (blue) and the National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS) (orange). MEPS obtains data on health conditions at multiple points during a 30-month period, whereas NAMCS and NHAMCS obtain data from medical records corresponding to a sampled visit. Data represent 3-year moving means. The vertical line at 2005 indicates the time that the boxed warning was implemented.
