Figure 5
Temporal trend in autism compared to temporal trend in cumulative amount of postnatal aluminum adjuvant administered to U.S. children by 18Â months of age. Red circles are years with published immunization schedules. Red triangles reflect educated guesses (see Additional file 1 ) for details) in gap years without published schedules. The red curve is lagged 1Â year because 18Â month-olds born, e.g., in 1994 will likely follow the 1995 schedule.
