Primary & Secondary Sources
In the September 2003 issue of Pediatrics, seven MDs and PhDs co-authored an article entitled, "Thimerosal and the Occurrence of Autism: Negative Ecological Evidence From Danish Population-Based Data." The article was 3 pages long and reported on their review of statistics of children diagnosed with autism in Denmark between 1971 and 2000. This would be the primary source.
In the December 2003 issue of Psychology Today, that magazine's News Editor wrote a description of the Danish study called "Autism Not Linked to Mercury." It was 4 paragraphs long. This would be a secondary source of information on the study.
